Answer:
Option B.
It has nucleus.
Explanation:
Giardia is a microscopic single celled prokaryotic organism that causes giardiasis. Giardiasis is an intestinal Infection in humans and dogs which is caused by giardia. It is an eukaryotic organism that have nucleus and nuclear membrane but it lacks other ORGANELLES that are present in Eukaryotic organisms. It causes diarrhoea in humans and woman's can get infected from dogs.
Answer:
B. It has a nucleus
Explanation:
All living organisms were classified into a large group called DOMAIN. These organisms were classified into two domains viz EUKARYA and PROKARYA depending on whether or not they possess a nucleus. Organisms in the Eukarya domain called Eukaryotes possess a membrane-bound nucleus that houses their genetic material (DNA) while organisms in Prokarya domain called prokaryotes do not possess a membrane bound nucleus.
Based on this, Giardia organism that is described to be an eukaryotic organism that causes illness in cats, dogs and humans is distinguished from any prokaryote by its possession of a membrane-bound nucleus in the cytoplasm of its cell. Any organism referred to as EUKARYOTIC must possess a NUCLEUS.

Final answer:
A cell with a high need for active transport requires many mitochondria to produce ATP (option c), the energy currency needed to power this process.
Explanation:
A cell that has a high need for active transport across its membrane will likely have many mitochondria to make ATP. Active transport is an energy-consuming process that moves substances against their concentration gradient.
The energy required for active transport is in the form of ATP, which is synthesized by the mitochondria in a process known as cellular respiration. Cells with a high energy demand, such as sperm cells or muscle cells, typically contain a higher number of mitochondria to meet these energy needs.
Furthermore, the mitochondria possess special carriers, like the ADP-ATP carrier protein, which aid in the movement of ATP out of the mitochondria and allow ADP in, maintaining the cellular energy cycle.

Answer:
1) the possible hypothesis is that the pickles are sour in taste.
2) we concluded from the above study is that most of the students said that pickles made from mango are sour in taste.
Explanation:
The possible hypothesis is that the pickles are sour in taste because in pickles mangoes are used when they are green in color and have sour taste so we can say that the pickles which is made from these mangoes are also have sour taste. There is a variation in opinion between students about the taste of mango pickle. Most of the students found the pickle sour in taste so we can choose the result of the majority of the students and make hypothesis accordingly.
1. Possible hypothesis: The taste perception of mango pickle may vary among individuals.
2. Conclusion: Taste perception of mango pickle is subjective, with some finding it sour while others perceive it as tasteless.
1. Possible hypothesis of the study:
- The hypothesis could be that the taste perception of mango pickle varies among individuals based on their sensitivity to sour flavors or other factors such as genetic predispositions, previous exposure to similar flavors, or individual taste preferences.
2. Conclusion from the study:
- The study suggests that taste perception of mango pickle is subjective and varies among individuals. Majority of the participants (7 out of 10) perceived the pickle as sour, indicating that the sour taste is predominant. However, a minority (3 out of 10) found it tasteless, suggesting individual differences in taste perception.

is a herd of bison, a community, ecosystem, habitat or population?
Answer:
A community (i think)
Explanation:
A herd of bison can be classified as a population in biological terms, because it represents a group of the same species living in the together. It would not be considered a community, an ecosystem, or a habitat due to the specific definitions of these terms.
Explanation:A herd of bison would most accurately be described as a population. In biological terms, a population is a group of individuals of the same species that live in the same area and interact with one another. A community, on the other hand, encompasses all the different species within a certain area.

What do prokaryotes have in common with eukaryotes?
O A. They both have a Golgi apparatus.
O B. They both have a liquid cytoplasm.
O C. They both have a nuclear membrane.
O D. They both have mitochondria.
Both prokaryotes and eukaryotes have a liquid cytoplasm
Prokaryotes and eukaryotes both have liquid cytoplasm where cell metabolism occurs. They do not share other features like Golgi apparatus, nuclear membrane, or mitochondria - these are exclusive to eukaryotes. option B is the correct answer .
Explanation:Prokaryotes and eukaryotes, despite their differences, share some common features. The main commonality between these two types of organisms is that they both have a liquid cytoplasm, where all of the cell's metabolic events occur. Neither a Golgi apparatus, a nuclear membrane, nor mitochondria are common to both, as these are typically features of eukaryotic cells. For instance, a nuclear membrane, which encloses the genetic material, is absent in prokaryotic cells and the Golgi apparatus, a packaging center for proteins, is also exclusive to eukaryotes. Similarly, mitochondria, the powerhouse of the cell, are only found in eukaryotes.

What is the main principle behind the law of conservation of matter?
A
Mass does not change phase during a reaction.
b
The total mass does not change during a reaction.
c
Heat is added during a reaction for the mass to remain constant.
D
Mass will always remain constant unless a change has occurred.
According to law of conservation of matter, mass can neither be created nor destroyed. Therefore option (B) is the correct answer.
What fundamental idea underlies the law of conservation of mass?The fundamental idea that underlies the law of conservation of mass is, a body's mass remains constant while it is in motion. This can be expressed in rate form as the rate at which the mass of a body changes over time to zero.
For instance, when coal is burned, the carbon atom in it transforms into carbon dioxide. The carbon atom transforms from a solid to a gas, yet its mass remains constant.
This proves that in a chemical process, no new or lost atoms are created. Instead, the atoms combine in a variety of ways to create goods.
Hence , option (B) which states that mass is conserved is the correct answer.

PLEASE HELP ILL MAKE YOU BRAINLIEST! Darwin suggested that evolution occurred at a steady, relatively slow rate. Today, scientists cite fossil evidence to support which revision of Darwin’s suggestion?
A. Evolution occurs slowly in the ocean and rapidly on land.
B. Evolution occurs slowly at the molecular level and rapidly at the organism level.
C. Evolution occurs slowly in some classes and rapidly in other classes.
D. Evolution may sometimes occur very rapidly, in any clade and at any time.
The correct option is D; Evolution may sometimes occur very rapidly, in any clade and at any time.
Darwin originally suggested that evolution occurred through a process of gradual change over long periods, a concept known as gradualism. However, the fossil record supports a different model called punctuated equilibrium, where long periods of little to no change are interrupted by bursts of rapid evolutionary change.
This alternative model accounts for the 'sudden' appearance of new species in the fossil record and proposes that speciation can occur relatively quickly under certain conditions, such as geographic isolation or significant environmental changes.

The oceans cover approximately 70% of Earth's surface and also contain about 97% of Earth's water
supply. This enormous amount of space provides habitats for a large number of diverse organisms.
However, organisms thrive in different areas. Which statement below best describes the
distribution of life in the ocean?
A) All species of aquatic organisms have adapted to all depths of the ocean and are distributed throughout.
B)Species which thrive in mid-ocean areas are those which are adapted to a warm environment rich in oxygen
and photosynthetic organisms.
C)Organisms which are able to survive in the deepest depths of the ocean must have adaptations that allow
them to live in cold dark environments under a lot of pressure.
D)The upper depths of the ocean are teeming with large organisms that need little sunlight and are not
dependent on autotrophs.
Answer:
C.) Organisms which are able to survive in the deepest depths of the ocean must have adaptations that allow them to live in cold dark environments under a lot of pressure.
Explanation:
Organisms which live in the deepest depths of the ocean receive little sunlight, so they must adapt to live in those cold conditions with a lot of pressure constantly on them. Basically, if a creature lives in a certain part of the ocean, they are most likely adapted enough to live in the conditions that their home has for them.
The best statement describing the distribution of life in the ocean is that organisms living in the deepest depths must have adaptations for survival, such as the ability to withstand cold, dark, and high-pressure conditions.
Explanation:The distribution of life in the ocean varies depending on factors like depth, temperature, light availability and nutrient availability. Not all aquatic species can survive in all ocean conditions. Thus, the best statement that describes the distribution of life in the ocean would be C), which states, 'Organisms which are able to survive in the deepest depths of the ocean must have adaptations that allow them to live in cold dark environments under a lot of pressure.' The extreme conditions of the deep ocean require specific adaptations for survival.
For example, many deep-sea organisms possess adaptations such as bioluminescence (the ability to create their own light), increased pressure tolerance and ability to deal with cold temperatures. Other examples of adaptations include having a slow metabolism to conserve energy, as food is scarce in those depths.

Strategies that can enacted in areas to eliminate non-point source pollution is participation in a stream cleanup program and compost yard and garden waste.
What is nonpoint source pollution?Nonpoint source pollution refers to diffuse contamination of water or air that does not originate from a single discrete source. This type of pollution is often the cumulative effect of small amounts of contaminants gathered from a large area.
Moreover, nonpoint source pollution occurs when runoff from rain and snowmelt carries pollutants into waterways such as rivers, streams, lakes, wetlands, and even groundwater.
Therefore, non-point source of pollution are pollution sources that are diffused and without a single point of origin or not introduced into a receiving stream from a specific outlet. The pollutants are generally carried off the land by storm water run- off.

Why is the pressure in the matrix high?
Help me!!
Answer:
It has more water molecules causing pressure to grow.
Explanation:
The pressure in the matrix, referring to a space within plant cells, is high due to the osmotic process, involving the movement of water from a lower to higher concentration. This builds up pressure in the cell, including the matrix, giving the plant rigidity.
Explanation:In the context of biology and specifically plant physiology, the term 'matrix' typically refers to the space within the chloroplast where the light-independent reactions of photosynthesis take place. The pressure in the matrix is high due to the osmotic process - the movement of water from a lower concentration to a higher concentration across a semi-permeable membrane. This process creates a build-up of pressure in the plant cells, including in the matrix.
The water-filled central vacuole exerts pressure against the cell wall - this is known as turgor pressure - giving the plant rigidity. As water moves into the cell, it increases the volume of the cytoplasm and the vacuole, thereby increasing the pressure within the cell, including the matrix.
