Answer:
The most appropriate option would be: The island will suffer a loss of native plant and animal species
Explanation:
A hurricane is a calamity that manifests itself in the form of great rain fall, strong winds and thunderstorm.
Hurricanes just like all other natural calamities cause a lot of destruction to the organisms living in an area, their habitats and become a source of introduction of certain invasive species.
If a Hurricance hits a small island in the Caribbean, there are a lot of chances that Island will lose a large amount of animals and plant species. The fact is that when a hurricane hits and goes, many not all specie re-emerge eco-system establishes due to process of succession. However, there are some native plant and animal specie that are native to a specific place like that Island, so there are more chances that after that large hurricane island will suffer a loss of native plant and animal species.
The climate of the Island will not be in a position to sustain the survival of all living organisms, therefore, some may starve and perish for always although some may recover too. Therefore, Option D seems best.

How is a plateau different from a fault-block mountain?
Answer:
A plateau is defined as a highland area that has a flat top topography, which has steep sides. These are often formed when the intrusive magma crystallizes before it comes out to the surface. The flat top surface of the plateaus are formed due to the continuous erosion process that has taken place since the geological time.
On the other hand, a fault-block mountain is a type of mountain which are formed due to the reverse faulting. It results from the upward movement of the blocks. These are jagged mountains and are formed from the compressional stress.
Thus, the plateaus are formed from the erosion process, and fault-block mountains are formed due to the compressional stress.
Which are the three main types of lipids
The three main types of lipids are:Triglycerides, Phospholipids, Steroids.
Triglycerides, also known as triacylglycerols or fats, are the most common type of lipids found in both plants and animals. They are composed of glycerol and three fatty acid chains. Triglycerides are the primary form in which energy is stored in the body. They serve as a concentrated source of energy and are stored in adipose tissue (fat cells) for future energy needs.
Phospholipids are a crucial component of cell membranes. Like triglycerides, they consist of glycerol, but instead of three fatty acid chains, there are two fatty acids and a phosphate group attached to the third position. The phosphate group makes one end of the phospholipid molecule polar (hydrophilic), while the fatty acid chains are nonpolar (hydrophobic). This unique structure allows phospholipids to form a phospholipid bilayer in cell membranes, providing a selective barrier for the cell.

The three main types of lipids are triglycerides, used for energy storage; phospholipids, which form cell membranes; and steroids, like cholesterol, involved in membrane fluidity and hormone production.
Explanation:The three main types of lipids are triglycerides, phospholipids, and steroids.
Triglycerides are composed of a glycerol molecule joined to three fatty acid chains. They serve as a major form of energy storage in both animals and plants.Phospholipids are made up of two fatty acid chains, a phosphate group, and a glycerol or sphingosine backbone. They are key components of the cell membrane, providing both a barrier and a matrix for other cell components.Steroids are a class of lipids characterized by a structure of four fused carbon rings. Cholesterol is a well-known steroid that plays a critical role in maintaining cell membrane fluidity and serves as a precursor for steroid hormones like testosterone.Lipids play numerous roles in biological systems, including energy storage, cellular structure, and hormone synthesis. They are generally hydrophobic and nonpolar, making them insoluble in water.

bones function as levers for the muscles to provide movement of the body What refers to reducing the angle of the joint thus bringing two bones closer together
The answer is D: Flexion.
Flexors muscles of the cause’s flexion, which reduces the angle of the joint and reduces the dis-tance between two bones. In this process, the muscle contracts and this brings the bones attached to the muscle close to each other due to the movement of the nearby joint. For example when flexion occurs at the elbow, the bones “Ulna” and “ Humerus” get close to each other .

Eukaryotic cells have organelles within each cell that are bound by their own lipid bi layer membrane ( t or f)
The answer is true; eukaryotic cells contain organelles that are each surrounded by their own lipid bilayer membranes, which include the nucleus, vacuoles, endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria.
The correct answer to this question is true. Eukaryotic cells are indeed structured with a number of organelles, each bound by a lipid bilayer membrane much like the cell's outer membrane. Key examples of these membrane-bound compartments include the nucleus, which contains the cell's genetic material, and vacuoles, which are storage organelles. Notable among other such organelles are the endoplasmic reticulum, Golgi apparatus, chloroplasts (in plant cells), and mitochondria. Each of these organelles has highly specialized functions; for example, mitochondria are known as the powerhouses of the cell because they produce energy through respiration. These organelles are often referred to as the 'little organs' of the cell, highlighting their specialized roles comparable to the organs in our bodies.

Calcium is an essential nutrient for all ages, but many marketing campaigns for high-calcium foods focus on childhood. Do you think there’s merit to telling children to get their calcium because it builds strong bones? Explain your response.
Answer:
Yes
Explanation:
, there’s merit to targeting children in marketing campaigns for high-calcium food. People reach peak bone mass at about age 30. If children don’t consume enough calcium, they may not build up enough bone density, which could cause them to be at risk for osteoporosis when they’re older.
There is a lot of merit in telling children to get their calcium in building strong bones because the increase in bone density by calcium stops between 25-30 years.
It is therefore for the children to take enough of calcium to make their bones
very dense and strong as attaining the age of 30 years means there will be
no change in the bone density regardless of the amount of calcium taken.
Intake of calcium at an early age also helps us plan for old age . At the age of
50 years and above , individual experiences bone loss which leads to
osteoathritis and other bone related diseases.

How do rock types contribute to the rate of weathering?
Porous minerals weather faster.
Harder minerals break apart more easily.
Minerals that dissolve easily weather slower.
Permeable rocks have less chemical reactions.
The correct answer is that porous minerals weather faster.
The process of weathering alter and disintegrates the rocks and minerals closer to or at the surface of the Earth. This process shapes the Earth's surface. The three kinds of weathering comprise biological, mechanical, and chemical. Weathering dissociates apart and erodes rocks and minerals.
The rocks are the symbols of strength and durability. The rocks are usually resilient to weathering. This confrontation relies on the mineral composition and mineral porosity. The physically soft or porous minerals are easily crushed and dissociated, while in case of harder minerals it is quite tough.

What would happen to a sample of your red blood cells if they were placed in a hypotonic solution?
Hypotonic solutions contain a low concentration of solute relative to another solution ( The cells cytoplsm)
Thus, when a cell in placed in a hypotonic solution, the water diffuses into the cell, which causes the cell to swell up.
The cell has lower solute concentration than the solution. So the solution is HYPERTONIC and the cell is HYPOTONIC.
As a result, a cell that does not have a rigid cell wall, such as a red blood cell, t'will most definitely swell and burst when placed in a hypotonic solution.
Final answer:
Red blood cells placed in a hypotonic solution will swell due to water rushing in, potentially causing hemolysis (bursting). In hypertonic solutions, they will shrink due to water loss.
Explanation:
When red blood cells are placed in a hypotonic solution, the concentration of solutes in the surrounding fluid is lower than those inside the cells. As a result, water rushes into the cells due to osmotic pressure. This influx of water causes the red blood cells to swell, potentially leading to hemolysis, which is the bursting of the cells due to excessive swelling. Conversely, if red blood cells are in a hypertonic solution, they lose water and shrink, which is known as crenation. Red blood cells function optimally in an isotonic environment, where the flow of water in and out of the cell occurs at equal rates, maintaining the normal shape of the cells.
Which method of birth control involves hormones?
Hormonal contraception methods, such as birth control pills, skin patches, injections, and implants, release synthetic hormones to prevent ovulation. Birth control pills come in two main forms and must be taken consistently. An intrauterine device (IUD) is another highly effective hormonal method, with proper placement and use required.
The method of birth control that involves hormones is known as hormonal contraception. Hormonal methods include a variety of applications such as birth control pills, skin patches, injections, and implants. These methods work by releasing synthetic hormones such as estrogen and progesterone to prevent ovulation.
An intrauterine device (IUD) is another highly effective hormonal method with a failure rate of less than 1 percent. IUDs are inserted into the uterus to prevent the implantation of a fertilized egg or, in the case of hormonal IUDs, to release hormones.

Mendelian inheritance states that traits are determined when offspring receive for each trait from . Traits can be , which means they can be seen and are capable of masking a different trait. Traits can also be , which means they can be masked. Alleles are different versions of the same in an organism.
Answers:
Mendelian inheritance states that traits are determined when offspring receive alleles for each trait from Parents.Explanation:
As per Mendel, all the traits which are present in an offspring are determined by specific genes which exist in alternate forms called alleles. For example: The height of a plant is a trait which is determined by alleles T for tall height and t for small height of same gene. The organisms acquire these alleles from parents (one allele from each parent).
--------------------------------------------------------------------------------
Traits can be Dominant which means they can be seen and are capable of masking a different trait.Explanation:
Dominant trait means when only a single dominant allele for the trait in an organism is enough for the organism to depict the trait. For example: In pea plant, purple flower color is a dominant trait over white. So any plant who contains only one dominant allele for purple (allele P) will have purple flowers but all plants that have two pp alleles will have recessive trait i.e White flowers.
-------------------------------------------------------------------------------------
Traits can also be Recessive which means they can be masked.As mentioned in above example, white flower color of pea plant is a recessive trait. Recessive means that if a plant has one copy of recessive and one copy of dominant allele, the dominant allele will suppress or mask the effect of dominant allele. Example is the above case of flower color when a plant with genotype Pp will have purple but not white flowers.
-------------------------------------------------------------------------------------------
Alleles are different versions of the same gene in an organism.Alleles are just alternate forms of a gene. For example if a plant height is determined by a gene L, it has two forms capital L and small l which are alleles of same gene. But capital L is for tall height and small l is for short height.

. How does temperature change with altitude in the troposphere?
The troposphere is hotter near the Earth's surface because heat from the Earth warms this air. As the altitude increases the number of air molecules decreases, the average of their kinetic energy decreases.
Does this help?
if it does please mark me brainliest! thanks:)
In the troposphere, temperature generally decreases with increasing altitude due to fewer molecules able to absorb heat. This is represented through the lapse rate, but can vary based on factors such as weather and location.
Explanation:
In the troposphere, the layer of the Earth's atmosphere closest to the surface, temperature generally decreases with altitude. This trend is due to the nature of the gases that make up the atmosphere and how they absorb the Sun's energy. At ground level, more molecules exist and are capable of absorbing and re-emitting heat. As we increase in altitude, there are fewer molecules to absorb heat, causing temperatures to drop.A common rate used to represent this change is the lapse rate, typically around 6.5 degrees Celsius per kilometer. However, actual values can fluctuate based on humidity, weather patterns, and geographic location.

Which combination of factors would curtail cell function?
I. pH
II. density
III. salinity
IV. temperature
The factors that can potentially curtail cell function include pH, density, salinity, and temperature. Changes in these factors can cause denaturation of proteins, cell dehydration, cellular damage, and decreased resource availability.
Explanation:The functioning of a cell is influenced to a great extent by its surrounding conditions, often falling within a narrow optimal range. The factors that can potentially impact and curtail cell function include the cell's pH, density, salinity, and temperature. Cells require specific physiological pH ranges for optimal function. Deviations can cause denaturation of cellular proteins and enzymes, leading to a loss in cell function. Similarly, high salt (salinity) concentrations can lead to cell dehydration. Cells function best at a body temperature of around 37°C. At higher temperatures, cells may get damaged or die. Similarly, cellular density also impacts function, with overcrowding leading to a decrease in resource availability thereby limiting function.

Condensed genetic material is called chromatin when not fully condensed and chromosomes during cell division, consisting of sister chromatids joined at a centromere.
Explanation:Condensed genetic material is called chromatin when it is not yet fully condensed into chromosomes, which occurs outside of cell division phases. During the cell division cycle and after DNA replication, this material coils and condenses further into the familiar X-shaped structures known as chromosomes. Each chromosome at this stage consists of two identical copies called sister chromatids, joined together at a region known as the centromere. It is important to note that the process of condensation is essential for the mitotic and meiotic processes that ensure genetic material is accurately divided between daughter cells.
