How would an increase in surface temperatures in the pacific affect sea otters and why would this happen?

Answers

Explanation:

How would an increase in surface temperatures in the pacific affect sea otters and why would this happen?

The water that sea otters live in is chilly, ranging from 35 to 60 degrees Fahrenheit—much too cold for humans. Otters don't have blubber to keep them warm like other marine mammals. Instead, they rely on their thick fur coat to maintain a constant body temperature of 100 degrees Fahrenheit.

Do environmental or genetic factors affect growth of organisms most?

Answers

Answer:

Examples of local environmental conditions could include availability of food, light, space, and water. Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. The environment in which an organism lives plays an important role in modifying the rate and extent of growth. Environmental factors may be either physical (e.g., temperature, radiant energy, and atmospheric pressure) or chemical. Organisms and the cells of which they are composed are extremely sensitive to temperature changes; as the temperature decreases, the biochemical reactions necessary for life occur more slowly. A lowering of the temperature by 10° C (18° F) slows metabolism at least twofold and often more.

I copied this stuff from a bunch of different biology websites. It doesn't answer your exact question but I would have to say based on what I typed here it would be the environment that affects the growth of an organism more.

What Pattern of inheritance is that?
sex-linked
Co-dominant
Incomplete dominance
O polygenic recessive

Answers

Answer: Polygenic recessive

Explanation: Because polygenic dominance describes a relationship between the alleles of a polygenic trait where some alleles are dominant and others are recessive.

This is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).

What is Polygenic inheritance?

Polygenic inheritance can be described as the inheritance of traits that are governed by different genes and not just a single gene, and can also be referred to as non-Mendelian inheritance, where traits run like a bell. distributes the sizes and shows the different combinations such as dominant and recessive alleles.

Polygenic traits express several different phenotypes, or displayed characteristics where this inheritance is a type of incomplete dominance inheritance, where the expressed phenotype is a mixture of inherited traits.

Thus, this is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).

A
mitosis
B
M phase
C
anaphase
D
interphase

Answers

The answer is D interphase

The cell cycle phase that occurs immediately following cytokinesis is the interphase, which is in Option D because the interphase consists of the G1, S, and G2 and is constitutively called the preparatory phase.

What is the cell cycle's importance?

The cell cycle consists of the interphase and the division phase, and in the interphase, the cell spends most of the time preparing itself for the cell division and consists of the G1, S, and G2 phases. Following the interphase, the cell enters the division phase, which is mitosis or meiosis, and divides, with the daughter cells potentially entering the cell cycle via the interphase.

Hence, the cell cycle phase that occurs immediately following cytokinesis is the interphase, which is in Option D because the interphase consists of the G1, S, and G2 and is constitutively called the preparatory phase.

How could biotechnology lead to a decrease in the use of pesticides?

Answers

Plants can be genetically engineered through the use of biotechnology to be less susceptible to insects. This trait will make pesticide use less necessary.

This is the sample answer on edge.

This method combines the genetic productivity enhancement of plants with the management of their hazardous organisms.

How is biotechnology used?

Typically, agricultural biotechnology is utilized to boost plant production productivity to reduce the use of pesticides.

In agriculture by applying biotechnology, pest management and the use of pesticides will be reduced for modified plants.

А
electron, proton, nucleus, neutron
В.
neutron, proton, nucleus, electron
С.
proton, neutron, electron, nucleus
D
nucleus, neutron, proton, electron

Answers

Answer:

nucleus, neutron, proton, electron

Explanation:

The list that correctly orders the parts of an atom from heaviest to lightest

in mass is as follows:

nucleus, neutron, proton, electron

The nucleus of an atom is composed of a tightly packed proton and

neutrons.

This makes the nucleus very dense and small. The nucleus are surrounded

by a negatively  charged electron.

The nucleus contribute to most of the weight of an atom.

This makes the nucleus the heaviest.

The neutron  is found in the nucleus of an atom. The neutrons are

electronically neutral.  The neutron are slightly heavier than proton.

Therefore, the neutron is the second heaviest part of an atom.

The proton is found in the nucleus of an atom. They a positively charged.

The proton is the third heaviest.

The electron revolves around the nucleus and are very light. In fact the

nucleus contributes to 99.9 % of the weight of an atom. This shows how

light the electrons are.

Therefore, the order from the heaviest to the lightest is as follows:

nucleus, neutron, proton, electron

The word novel is borrowed from the Italian word novella (Henry 235). Defining exactly what a novel is can be hard work. The standard dictionary definition is "a fictional prose narrative of considerable length, typically having a plot that is unfolded by the actions, speech, and thoughts of the characters" ("Novel"). Novels in some way represent life. The representations, however, occur in a narrative about life and experience. Since the novel can represent life, such fiction can be serious. The seriousness begins when the novel deals with humankind in a way that shows its importance and significance within the fictional world of the novel. The world of a novel varies greatly from author to author because each writer creates a new fictional world for a new work. That world may be all the relationships of a whole nation or of a very small town. That world may be as confined as the captain's cabin on a ship or as open as a little island. That world may also be as withdrawn as the farthest recesses of the human mind. Novels are important as they entertain and instruct the readers through a variety of life experiences.What is the author's tone toward the subject?
