Use natural light and grow your own vegetables

Answer: Use natural light instead of electric lights during the day.

Grow your own vegetables in a garden instead of shopping for them.

Explanation:

Green house gases are the gases which trap the heat from sunlight causing the retention of heat in the atmosphere. This causes global heat.

The use of natural light will reduce the dependency of fossil fuel for the generation of electricity. Hence, the burning of fossil fuel and generation of greenhouse gases such as carbon dioxide, carbon monoxide and others will not release.

Growing own vegetables will reduce the carbon dioxide levels in the atmosphere. Hence, will reduce the green house gas abundance in the atmosphere.

B. It insulates the fish from the cold air above

Just like an igloo

Answer:

Option B, It insulates the fish from the cold air above

Explanation:

Water bodies in cold climatic regions have frozen ice at their top. Basically,  this ice (frozen water) entraps air pockets inside it which acts like an insulator and prevent the aquatic plants and animals from the extreme cold climate. Thus, ice on the surface of any water body protects the species beneath the ice layer from extreme cold climatic conditions. For example Michigan lakes and ponds  get freeze during cold climatic condition.

Option B is correct

Answer:

D

Explanation:

Each allele from one parent randomly segregates into the gametes during gamete formation, resulting in each allele being present in half of the parent's gametes. Thus option D is correct.

The two alleles for each trait segregate, or separate, during the development of gametes, and that the alleles will randomly join with other alleles throughout the development of new zygotes.

With two copies of each gene, the law of segregation guarantees that either allele can be passed down from a parent. The likelihood that each allele will form a zygote will be equal for both.

The genome is carried by sexually reproducing organisms in two identical copies. Each gamete carried a copy that was inherited from each parent.

When both copies of the genome are present, these organisms are said to be diploid, and when only one copy is present, they are said to be haploid.

Therefore, offspring receive one allele for each trait from each parent, and the allele from each parent is distributed randomly.

The significant characteristic shared by both plants cells and photosynthetic bacteria is the ability to perform photosynthesis within specific structures; namely, chloroplasts in plants and thylakoids in bacteria.

The main characteristic shared by both plant cells and photosynthetic bacteria is the ability to carry out photosynthesis. Photosynthesis is a process used by these organisms to convert light energy, most commonly from the sun, into chemical energy that can be later released to fuel the organisms' activities. Plants do this within an organelle called chloroplasts, which contains chlorophyll, the pigment that captures the light energy. Similarly, photosynthetic bacteria, such as cyanobacteria, have special membrane structures known as thylakoids where photosynthesis occurs. Therefore, the possession of structures for conducting photosynthesis, i.e., chloroplasts in plant cells and thylakoids in photosynthetic bacteria, is the characteristic that is shared between plant cells and photosynthetic bacteria.

The Both plant cells and photosynthetic bacteria share the characteristic of conducting photosynthesis to generate energy from sunlight.

Photosynthesis is a crucial process that converts light energy into chemical energy, primarily facilitated by the pigment chlorophyll.

In plant cells, chlorophyll is found within chloroplasts, specialized organelles responsible for photosynthesis.

During photosynthesis, light energy is absorbed by chlorophyll, initiating a series of chemical reactions that result in the synthesis of glucose and other organic compounds.

This process is fundamental for the production of energy-rich molecules that support the growth and development of both plants and photosynthetic bacteria.

The shared ability to carry out photosynthesis highlights a common evolutionary adaptation among these organisms, allowing them to harness solar energy for their metabolic needs.

While plant cells and photosynthetic bacteria differ in their cellular structures and evolutionary history, the convergence in utilizing photosynthesis underscores the importance of this process in sustaining life on Earth.

Explanation:

there are some of those viruses where it can be quite potent. Some viruses, such as the rhinoviruses, seldom cause serious illness. But others, such as parainfluenza and respiratory syncytial virus, can lead to severe lung infections in young children.

Answer:

B. Colds can be caused by hundreds of different viruses.

Explanation:

The common cold is a benign viral infection of the upper respiratory tract, which mainly affects the nose and throat. The most common symptoms are: nasal congestion, runny nose, sneezing and sore throat. This is one of the most common diseases that exist. Eventually, everyone will get a cold more than once in their life.

More than 200 viruses can cause colds, all of which are respiratory transmission, which makes contagion extremely effective. Cold viruses enter the body through the lining of the mouth, eyes or nose. The most common is to bring the contaminated hand to the face. This port carries viruses acquired by manual contact with colds or contaminated objects.

There is also the possibility that viruses reach these mucous membranes, through invisible droplets, suspended in the air, after a person with a cold sneezes, coughs or talks. It is estimated that for this form of contagion, there is a need to be less than one meter from the infected person.

Answer:

408 grams therefore has a volume of (408/11.35) = 35.947cc. It displaces 35.947cc of water, = 35.947 millilitres. When lead is put in water, it will displace same volume of water. Therefore, 408 g of lead will displace 36 ml of water.

The volume of 408g of lead is approximately 36 ml. This means that when this quantity of lead is dropped into water, it will displace approximately 36 ml of water.

To answer this question, we need to use the concept of density. The density of lead is approximately 11.34 grams per cubic centimeter (g/cm³). The volume of an object can be determined by its mass divided by its density. So, the volume of 408g of lead would be: 408g / 11.34 g/cm³ = 35.97 cm³.

Since 1 cubic centimeter is equivalent to 1 milliliter, you would displace approximately 36 milliliters of water (rounded to the nearest whole number) when you drop the 408g of lead into it. Keep in mind this calculation assumes that the lead is solid and has no hollow spaces within it.

The correct order of stages in mitosis is:

Prophase

Metaphase

Anaphase

Telophase

Cytokinesis.

Mitosis is a fundamental process in eukaryotic cell division, ensuring the accurate distribution of genetic material to daughter cells.

The sequence of stages in mitosis is intricately orchestrated, each phase serving a specific purpose in the division process.

Prophase: Chromosomes condense and become visible.

The nuclear envelope disintegrates .Mitotic spindle fibers begin to form.

Metaphase: Chromosomes align along the cell's equator, known as the metaphase plate. Spindle fibers attach to the centromeres of each chromosome.

Anaphase: Sister chromatids are pulled apart by spindle fibers toward opposite poles of the cell.

Each chromatid is now considered an independent chromosome.

Telophase:

Chromosomes reach the opposite poles and de-condense. A new nuclear envelope forms around each set of chromosomes.

Mitotic spindle fibers disassemble.

Cytokinesis:

The physical division of the cell into two daughter cells.

In animal cells, a cleavage furrow forms, pinching the cell membrane.

In plant cells, a new cell wall, known as the cell plate, develops to separate the cells.

During telophase, the formation of a new nucleus marks the final stages of mitosis.

This meticulous sequence of events ensures that each daughter cell receives an accurate and complete set of genetic material.

Mitosis is essential for growth, development, and tissue repair in multicellular organisms.

With increasing distance from the earthquake, the time difference between the arrival of the P waves and the arrival of the S waves increases. Put more simply, the higher the time between the S and P waves (the S-P interval), the farther the distance. Describe the process of triangulation to locate an epicenter.

Brainliest?

The time interval between the arrival of the P waves and the arrival of the S waves is longer the more away you are from the earthquake. Simply said, the distance increases as the S-P interval (the amount of time between the S and P waves) increases.

The epicentre is the location on Earth's surface that is immediately above the location underneath (also known as the focus) where the earthquake's fault rupture starts. The area immediately surrounding the epicentre may not experience the worst impacts of the earthquake.

By calculating arcs from three or more seismic observatories, the epicentre may be found. The arcs' radii are proportional to how long it takes seismic waves to travel from the focus to each station. The epicentre is where the arcs' junction occurs. In computer programmes, the analogous algebraic analysis is carried out.

Therefore, the time interval between the arrival of the P waves and the arrival of the S waves lengthens as the distance from the earthquake rises. Simply put, the distance increases as the duration between the S and P waves (the S-P gap) increases.
