When a lake freezes, how does the density of water prevent all of the living organisms in the lake from freezing as well?
Due to surface tension the lake freezes partly because of the pressure.
What is freezing process?Freezing is the process in which phase change or state change takes place it means that a process in which a liquid change into solid.
Freezing process can be achieved by extracting heat i.e or removing latent heat, latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without change in temperature.
So, during the formation of ice from water, heat is removed from water at zero degree celsius at constant temperature, then water changes into ice.
A freezing or solidification process may occur in a liquid, initially at a uniform temperature, either above or at the the freezing temperature or fusion point.
Therefore,due to surface tension the lake freezes partly because of the pressure.

While listening to a client's chest, the nurse notes a rub during inspiration and expiration with a grating sound. when communicating to the health care provider, what should the nurse request in the sbar communication?
When communicating to the healthcare provider, the nurse must report pleural friction rubs during inspiration and expiration because this occurs when the pleural layers or linings are inflamed due to loss of lubrication. The client must be further assess for possible pulmonary infarction or pneumonia and the nurse must recommend for a chest x-ray of the client to evaluate the condition.

What is an advantage of using transgenic bacteria to produce human proteins? (1 point)
The human proteins produced by transgenic bacteria work better than those produced by humans.
Transgenic bacteria can produce human proteins in large amounts.
The human proteins produced by transgenic bacteria last longer than those produced by humans.
Transgenic bacteria can produce human proteins used to make plastics.,
Final answer:
Using transgenic bacteria to produce human proteins offers the advantage of large-scale production, providing a plentiful supply of medically important proteins such as insulin and growth hormones.
Explanation:
An advantage of using transgenic bacteria to produce human proteins is that they can produce these proteins in large amounts. Biotechnology allows for the transformation of bacteria to manufacture human proteins such as insulin, cytokines, and human growth hormone, which are of great medical value. With the rapid replication rate of bacteria and the use of genetic engineering, it is possible to produce these essential proteins more efficiently and in greater quantities than can be achieved through traditional methods.
Notably, the proteins produced by transgenic bacteria are not necessarily superior in quality or longevity compared to those produced by humans; the primary benefit lies in the volume and speed of production. Additionally, genetic engineering and recombinant DNA technology allow for the production of medically necessary proteins that are identical to human proteins, reducing the risk of allergic reactions and improving treatment effectiveness.

What could happen to target cells in an animal that lack receptors for local regulators?
a. they could develop normally in response to neurotransmitters instead.
b. they would not be expected to multiply in response to growth factors from nearby cells.
c. they could compensate by receiving nutrients via an alpha factor.
d. they would divide but could never reach full size.
e. hormones would not be able to interact with target cells?
Final answer:
Correct answer is option b) they would not be expected to multiply in response to growth factors from nearby cells. Lack of receptors for local regulators would prevent target cells from responding to specific growth factors, meaning the cells would not get signals to divide and multiply. Receptors are essential for cells to respond to hormones and other signaling molecules.
Explanation:
If target cells in an animal lack receptors for local regulators, such as certain growth factors or hormones, the cells would not be able to respond to those signals. This could mean that the cells would not receive the necessary instructions to proliferate, differentiate, or perform specific functions. Specifically, option b) they would not be expected to multiply in response to growth factors from nearby cells, correctly explains the situation. Without the ability to respond to growth factors due to the absence of appropriate receptors, these target cells will not get the signal to divide and multiply as they normally would.
Target cells without receptors for [Option b] local regulators would not multiply in response to growth factors from nearby cells.
This is because any cellular response to external signals like growth factors requires the presence of particular receptors. The cells are unable to detect or respond to these signals without these receptors, preventing the anticipated proliferative response. Target cells with particular receptor proteins are typically the targets of hormones and other signals. A signal transduction pathway, which may involve alterations in gene expression and cellular behavior, cannot begin without these receptors. Cells involved in growth and development, for instance, heavily rely on these receptors to appropriately respond to growth factors.do perch and chimps share a common ancestor?
Answer:
The correct answer for: do perch and chimps share a common ancestor? Is yes and its name is: choanoflagellates
Explanation:
To understand the answer we need to analyze its context. First of all, this is only theory and yes, it is believe that choanoflagellates are the closest unicellular ancestors to animals. If this is correct yes all animals on earth share the same ancestor and are those guys. However, if we turn into the primate mammal family species and the pikaia fmily species share direct ancestors the answer is no. But as animals, we do share an ancient ancestor. So yes, they share one ancestor. Even though it's a pretty old one.

biological evolution common descent
Answer: common descent
Explanation:
The theory of common descent suggests that the organisms which are found today has been evolved from the organisms used to live in the past. It is a scientific theory which explains the fact that all living organisms that are found on earth are the descendants of a single common ancestor that is the primitive organism. This has been confirmed by analyzing the features present in the fossil remains of the primitive organisms which are found to be nearly similar to that of the organisms living today.
in the adult body, food energy not stored as fat or glycogen is lost as ____. heat photons carbon dioxide electromagnetic radiation methane
Answer:
Heat
Explanation:
To obtain the energy from food and store it as either fat or glycogen a series of metabolic chemical reactions take place in the cells of the organism.During this chemical reaction, a large amount of heat is also produced that is either used to maintain the core temperature of the body which is an essential requirement or is lost through the skin to the environment.This is the reason why the energy conversion is not 100% efficient because heat losses are always there.It is estimated that around 75% of the energy that is obtained from food is lost as heat and only 25% gets stored.As a result of advances in biotechnology, ________ may become a thing of the past disease pollution hunger joint replacements
