8. Explain why mammals have specialized excretary organs but plants do not have.
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
They consume food and they have much higher metabolism. That means that more waste products are produced. Plants can use much of the waste produced and it is in fact raw material. Animals don't normally produce their own chemicals from scratch like plants normally do so they can't just recycle the waste. They need to remove it. About the only waste plants need to get rid of is excess oxygen produced during the day. That is actually three reasons but recycling is related to plants not consuming but making their own chemicals from scratch. In a way it pretty much comes down to one main reason.

Students construct a graphic organizer to illustrate the different levels of biological organization.
Organ → Organ system → X → Population → Community
Which term does the letter X represent in the graphic organizer?
A) Cell
B) Organism
C} Ecosystem
D) Biosphere
Answer:
B--Organism
Explanation:
Different levels of biological organization start from the least complex object and end at the most complex. Every object has objects preceding it that it is made up of.
In this question, the organ system is made up of several organs. A community is made up of several populations of different people. Think about this now: what makes up a population and is made up of organ systems? The most logical answer here according to the flow is B--an organism. An organism is made up of organ systems and makes up a population, which in turn allows several populations to make up a community.
Various levels of biological association begin from the smallest complicated entity and end at the most intricate is called biological organization. Every entity has things preceding it that it is composed of.
The organism is the letter X represent in the graphic organizer.
What is the biological organization?A certain level of the organization is established in the biological living beings and communities. The level of the organization starts from the most simple and the uncomplicated entity to the more complex beings and associations.The organ in this illustration is the small and complicated entity that links and forms the organ systems. Different organs make up the organs system like the esophagus, stomach, intestine makes up the digestive system.Various organs system combines in a body to form an organism like reproductive, circulatory, digestive etc. organs system make the organism as a whole.Various organism combines and interacts with each other to form a population of the same species in a defined area.A population of various species combines to form a community that lives together depending on each other for factors like food, shelter, water, nutrients etc.Therefore, option B is correct.

“The movement of cytoplasm is due to the movement of chloroplasts in the living cells of onion plant”, “while the movement of chloroplasts is due to the movement of cytoplasm in the living cells of bean plants”
which statement is correct and which one is wrong
''The movement of chloroplasts is due to the movement of cytoplasm in the living cells of bean plants'' is the correct statement.
The above statement is correct because chloroplast is an organelle which moves in the cell through the medium known as cytoplasm. Cytoplasm is a thick fluid that fills every type of cell and organelles are floating as well as suspended in this fluid.
All organelles such as the nucleus, endoplasmic reticulum, chloroplast and mitochondria etc are located in the cytoplasm. The portion of the cytoplasm except the organelles is called cytosol so we can conclude that chloroplast is an organelle which moves within the cell with the help of cytoplasm.

What is the definition of epistasis?
A. when the allele of one gene changes the phenotype of another gene
B. when the allele of one gene masks the genotype of another gene
C. when the allele of a gene changes the phenotype of another allele of that gene
D. when the allele of one gene masks the phenotype of another gene
The definition of Epistasis in gene biology is Choice D: when the allele of one gene masks the phenotype of another gene
Definition:
When the phenotypic effect of alleles at one gene are masked by alleles of another gene.
In essence, a gene is said to be epistatic when its presence suppresses the effect of a gene at another locus.
It is important to know that Epistatic genes are often called inhibiting genes because of their effect on other genes which are described as hypostatic.
Additionally, there are six common types of epistasis gene interactions:
Dominant Dominant inhibitory, Duplicate dominant, Duplicate recessive, Polymeric gene interaction, Recessive.Read more:

Which cell type undergoes terminal differentiation?
Stem cells are the only form of cell that can differentiate into more specialized cell types. Therefore, they undergo terminal differentiation.
What is terminal differentiation?As cells migrate to the surface and fully differentiate, i.e., as they keratinize and eventually die, this process is known as terminal differentiation. Terminal differentiation is a method of describing that the cells change their phenotypic traits.
During the process of terminal differentiation, several cell types (such as neurons, skeletal and cardiac myocytes, adipocytes, and keratinocytes) acquire specific tasks and ultimately exit the cell cycle. This process may be observed in neurons, adipocytes, and keratinocytes.

Why are flood plain soils particularly fertile
Answer:
Due to the deposition of silt.
Explanation:
The Floodplain is a generally flat area of land next to a river or stream. When the river floods, water containing sediments and particles from the upper course and middle course of the river gets washed onto the Floodplain. The nutrients front these sediments and the water is absorbed into the soil for it's enrichment and fertilisation.

How have rising ocean temperatures affected coral communities?
A. Corals become less photosynthetic as the surrounding temperature increases.
B. Corals find fewer food sources when algal blooms increase due to warmer waters.
C. Corals attract fewer algal species when they become warmer.
D.Corals become bleached as they expel algae with increased temperatures.
Answer: D.Corals become bleached as they expel algae with increased temperatures.
Explanation:
As ocean temperatures rise, it can stress coral polyps, that causes them to lose algae. As a result, there is "coral bleaching". It is called that because the algae gives coral its color. When all the algae is gone, the coral is white.
The bleaching of corals in the world, are due to the increase in sea temperatures, but to understand how this changes corals, we need to know that.....
Coral bleachingCoral bleaching is a serious ecological problem mainly related to the increase in ocean water temperature. This problem can occur transiently or fatally, killing the coral. In the bleaching phenomenon, the corals become translucent, making it possible to verify the calcium carbonate skeleton of these animals. This happens because of the expulsion of zooxanthellae algae or because of the loss of pigment from these algae, which live in a mutualistic association with the coral.
Question answerD.Corals become bleached as they expel algae with increased temperatures.with this information, we came to the conclusion that with the increase in sea water temperature, algae that are associated with corals are expelled.
