Animals,plants, fungi, microorganisms
Answer:animals,plants,fungi,microoganisms
Explanation:
why aren't all the cells in our body totipotent our entire lives
Answer:
somatic cells have highly specific functions
Explanation:
In our body, the major part of cells is irreversibly differentiated into somatic cells. From a cellular point of view, this process of differentiation seems to be an evolutionary disadvantage. However, cellular differentiation is a process aimed at exploiting the genetic variation in order to obtain a highly specialized cell type that is capable of carrying out a specific cellular function. For example, keratinocytes are highly specialized epithelial cells that function by separating the organism from the surrounding environment.

Compared to dry environments, evaporation of sweat is ________ in humid environments, resulting in _______ body cooling.
Answer:
less; reduced
Explanation:
Compared to dry environments, evaporation of sweat is less in humid environments, resulting in reduced body cooling.
In dry environment, the body sweats more in order to compensate for the rate at which evaporation occurs from the surface of the skin. However, in humid environment, sweating is reduced because the rate of evaporation of water from the surface of the skin is not as much as in dry environment. Since evaporation causes cooling, it means that there would be reduced body cooling in humid environments.
Milk snakes are a species of nonpoisonous snakes that inhabit a wide geographical range throughout North America.

Answer:
proximate explanation
Explanation:
In biology, a proximate explanation refers to an event that is directly responsible for producing a specific result. A proximate explanation allows to explain a particular biological phenomenon immediately associated with physiological factors. In sociology, a proximate explanation enables understanding of human behavior by their more immediate factors. On the other hand, an ultimate explanation is believed to be the real cause of the observed results.

a group of students is observing these two species of squirrel in forming conclusions about how they are alike and different which type of investigation is the group doing
Answer:
Although there are no options but this investigation is a COMPARATIVE investigation
Explanation:
Scientific investigations aims at satisfying a curiosity or a way of explaining natural phenomena. There are three types of investigations viz: descriptive, comparative and experimental investigations.
Comparative investigation is a type of investigation that involves collecting data on different organisms, locations etc for the sole purpose of comparing. It aims at confirming if there is a relationship between i.e. similarities/differences. In this question, two species of squirrels are being observed for their similarities and differences i.e. the aim of the investigation is COMPARISON. Hence, it is an example of comparative investigation

why grapes swell when placed in water
When grapes are soaked in water, the grapes then swell up because grape's cells have a high concentration of solutes in comparison to the water. In other words, grapes have low concentration of solvent (that is water molecules ) in comparison to the concentration of solvent in water. In this situation, there will happen a process known as osmosis in which water molecules moves from a region of concentration of water to a region of low concentration of water through a semipermeable membrane. (the cell membrane of the grape's cell is also semipermeable,which only allows solvent molecules to pass through it)

Kudzu is a vine that was brought to the us from japan to prevent erosion once here kuduz became invasvie what role does kuduz most likely play in the environment in the us
Answer:
Kudzu in the United States has become an environmental concern.
It is naturally coded to spread quickly. The advantage to that is that it was useful in the prevention of erosion and management of the landscape.
Presently, it is creating an ecological imbalance. Kudzu is very efficient at collecting and converting sunlight more than the local plant species and even tree plants. The competition from Kudzu is so tough, tree plants are being starved off of soil nutrients and sunlight and are unable to survive.
Even the wildlife are affected as the crops which they forage on cannot are outcompeted by Kudzu.
Cheers!
