If a population of medium sized rodents is placed under a selective pressure that yields both very large and very small individuals it was most likely _______.a. a stabilizing selection
b. a disruptive selection
c. a directional selection
d. not a natural selection event

Answers

Answer 1

Answer: If a population of medium sized rodents is placed under a selective pressure that yields both very large and very small individuals it was most likely b. a disruptive selection. Disruptive selection is the type of selection that favors the extreme traits or phenotype rather than the average ones.

O2 diffuses passively when produced inside the cell. O2 diffuses passively when converted to CO2. O2 is pumped in and forces CO2 out.

Answers

The correct answer is:

CO2 diffuses passively out of the cell. O2 in respiration is converted to water. O2 diffuses in to the cell.

Explanation:

Cellular respiration is the chemical reaction in which glucose and oxygen are converted into water, carbon dioxide, and energy (ATP). In this reaction, glucose and oxygen are reactants, while water, carbon dioxide, and energy (ATP) are products. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to change biochemical energy from nutrients into adenosine triphosphate and then discharge waste products.

CO₂ diffuses passively out of the cell. O₂ in respiration is converted to water. O₂ diffuses in to the cell.

Thus, The chemical reaction that turns glucose and oxygen into water, carbon dioxide, and energy (ATP) is known as cellular respiration.

Glucose and oxygen are the reactants in this process, and the products are water, carbon dioxide, and energy (ATP).

To convert biochemical energy from nutrients into adenosine triphosphate and eventually release waste products, cells of organisms undergo cellular respiration, a series of metabolic reactions and activities.

Thus, CO₂ diffuses passively out of the cell. O₂ in respiration is converted to water. O₂ diffuses in to the cell.

Which type of water is the least dense? A.
warm, salty water

B.
warm water with no salt

C.
cold water with no salt

D.
cold, salty water

Answers

B, cold with a high salt content, I believe. Since density is mass divided by volume, adding salt would increase mass. Temperature is related to kinetic energy and the distance between molecules/atoms of a substance. The hotter the substance, the more distance there is between particles. Generally cold water is more dense. Hope i helped :D

Which of the following statements about the effects of pollution on marine ecosystems is true?a.
Burning fossil fuels causes a direct increase in the temperatures of ocean water.
b.
Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic.
c.
Pollution in marine ecosystems causes a decrease in the formation of algal blooms.
d.
Addition of warm water has no effect on marine ecosystems.

Answers

Answer is b. Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic.

Burning of fossil fuels release carbon dioxide and other harmful gases in the atmosphere. Carbon dioxide gets dissolves in the ocean to form carbonic acid. Due to formation carbonic acid, the pH of ocean water changes slightly. The average pH of ocean water was 8.2 slightly basic. Now it 8.1, it means there is 25 % increase in acidity of ocean water.

The True statement about the effect of pollution on marine ecosystem is : Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic ( B )

Fossil fuels

When we Burn fossil fuels carbon dioxide and other harmful gases are released into the atmosphere.The Carbon dioxide gases gets dissolves in the ocean to form carbonic acid. The formation of carbonic acid leads to a change in the pH level of the ocean.

Hence we can conclude that The True statement about the effect of pollution on marine ecosystem is : Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic ( B )

A frustrated mother with a 9-month-old baby comes to the clinic because her son is refusing all solid food. When talking with this mother, the nurse discovers the mother has struggled with a weight problem all her life, which she attributes to being forced to eat even when she was full. Not wanting to treat her child the same way, each time her son pushes food away with his tongue she believes that he doesn't want it. Which statement would be most appropriate for the nurse to say to this mother?

Answers

Answer:

The mother should know that her child at this age is not able to eat solid foods.

Explanation:

The mother needs to know that her child is not having or struggling with any weight problem and he/she can not eat solid foods. She needs to change her way of feeding him/her and start to prepare for him/her soft bread, cooked noodles, dairy foods..etc.

Which statement describes an effect of naturalselection on a species?
(1) It favors the survival of certain members
of the species and results in a change in
the proportion of individuals with highly
adaptive traits.
(2) It provides feedback mechanisms for members
of a species and results in a change in the
proportion of individuals with homeostatic
controls.
(3) It leads to reproduction with other species,
increasing the number of different adaptations.
(4) It increases competition between populations
that occupy different niches, increasing the
chance of extinction of the less-adapted
species.

Answers

I believe 3 only because natual selection can speed up reproduction so more mutations can be formed causing more genes so more genetic diversity can be caused.
