Nathan is comparing the cells from a species of amoeba with a species of bacteria. Both species are unicellular, meaning individuals exist as a single cell. Which characteristic of the cells should Nathan expect to be the same in both species?


A. The size and shape of the cell

B. The method of reproduction, or making more cells of the species

C. The organization of DNA into structures such as chromosomes and the cell nucleus.

D. The genetic code that has used by DNA and RNA to direct protein synthesis

Answers

Answer 1

Given what we know, we can confirm that Nathan can expect the means of reproduction to be the same in both species, meaning that the correct answer would be option B.

Why is option B the correct choice?

When dealing with unicellular organisms, many aspects will always remain the same between the distinct species. One such aspect is the reproduction method used universally by all unicellular species, that being reproduction through binary fission. The organism replicates its DNA and then divides into two identical cells.

Therefore, we can confirm that Nathan can expect the means of reproduction to be the same in both species, meaning that the correct answer would be option B.

How can cells from the same organism have such different shapes and functions?

Answers

Answer:

As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity. B Mutations in the cells' nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.

Explanation:

Answer:

Because cells are not only characterized by by their genetic material and other interior components, but also by the genes they express. Cells have to fulfill multiple different functions to be able to build complex multicellular organisms. Differently expressed genes lead to different proteins made in the cell, which leads to different morphology, shape or function. For example melanocytes in the skin are highly specialized cells which mostly make the pigment melanin. Plasma cells on the other are highly specialised for making antibodies.

Based on your knowledge of energy flow and light absorption, which color(s) of light will provide energy for photosynthesis? (select all that apply) question 2 options: red orange green blue violet

Answers

Answer:

RED and BLUE

Explanation:

Special pigments in chloroplasts of plant cells absorb the energy of certain wavelengths of light, causing a molecular chain reaction known as the light-dependent reactions of photosynthesis. The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm).

Red and blue as the best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm).

Which colors of light are most absorbed for energy during photosynthesis?

Chlorophyll is the pigment responsible for photosynthesis. It absorbs most energy from wavelengths of violet-blue and orange-red light.

The chlorophyll pigments mainly absorb blue and red light. Maximum absorption is in blue light but maximum photosynthesis occurs in red light

In any population, some individuals will have more kids than other individuals (just by chance). Some of those individuals will be "lucky" and survive. Explain the cartoon and how it shows this idea.​

Answers

Answer:

By people stepping on the little bugs, it kills them. and when they are born some will die and others won't

Explanation:

The cartoon refers to the principle of natural selection, which operates in many species, including bugs.

When individuals of a species reproduce, their offspring inherit certain traits or characteristics that can be advantageous or disadvantageous. In the case of bugs, some may have stronger exoskeletons, faster reflexes, or better camouflage, which can help them survive being stepped on or avoid being noticed by predators.

As a result, those bugs with advantageous traits are more likely to survive and reproduce, passing on their favourable characteristics to the next generation, while those without these traits are more likely to die. This is an example of natural selction.

Answers

Uniporter allows the movement of a subtance in one direction, symporter two molecules in the same sense and antiporter two in opposite sense. Nicotinic acetylcholine receptors are linked to symporters to allow the movement of neurotransmitters. G protein function is coupled to second messengers such as cyclic AMP, active transport allows the movement of substance again a concentration gradient and reuptake mechanism involves symporter transport.

What are uniporter, symporter, and antiporter?

The terms uniporter, symporter, and antiporter make reference to different types of channel proteins located in the cell membrane which allows the movement of molecules through this selectively permeable barrier.

Moreover, nicotinic acetylcholine receptors are receptors that bind to certain neurotransmitter chemical messengers such as acetylcholine in order to allow the movement of ions through the membrane.

Therefore, with this data, we can see that uniporter, symporter, and antiporter are different classes of channel proteins in regard to the movement of molecules in and out of a selectively permeable barrier (i.e. the cell membrane).

What would happen if the concentrations of carbon dioxide and methane rose too high?

Answers

Answer:

I'm assuming this means concentrations of the atmosphere*

Explanation:

Carbon dioxide are both considered greenhouse gasses. This means whenever they are in the atmosphere, they absorb heat from the sun and trap it within the atmosphere. In general, greenhouse gasses are a good thing. They trap heat in the Earth during nighttime so we do not freeze when we don't have the sun. However, since the Industrial revolution, the overuse of fossil fuels which are made of carbon and sometimes have high methane concentrations have lead to an excess amount of these gasses in our atmosphere. If concentrations become too high, the Earth's climate will continue to display higher average temperatures, leading to a complete change in our environments as once glacial areas will begin to display more temperate climates, and temperate and warm climates will become even hotter. Ecosystems in every area will be severely damaged, with many species likely facing extinction. Additionally, sea levels will rise much higher, both due to the melting of glaciers into the ocean and also because warmer climates will make the ocean warmer, meaning the molecules of water will spread farther apart and increase the volume of the ocean.

Explanation:

New York is composed of sediments that have metamorphed around 400 to 500 million years ago during the Acadian and Taconic orogenies.

Bedrock in the area of Binghamton, New York, consists of sedimentary rock layers. So, the correct option is B.

What are sedimentary rock layers?

The formation of sedimentary rocks involves the accumulation or deposit of mineral and organic particles at the Earth's surface, following by cementation. The mechanisms that lead to the accumulation of these particles are collectively referred to as sedimentation.

Sediment refers to the little particles that make up sedimentary rocks and can be either geological detritus (nitrogen and phosphorus) or biological detritus (organic matter). Sandstone, limestone, and mud are examples of typical sedimentary rocks.

These rocks frequently begin as sediments that are transported by rivers, then are dumped in lakes and oceans. The sediments become dry and cement together to form rock when they are buried. Volcanic ash can be found in tuffaceous sandstones. Bedrock in the area of Binghamton, New York, consists of sedimentary rock layers.

Astronomers estimate that the Sun's luminosity will increase by about 6% every billion years. This increase might seem slight, but it will render Earth inhospitable to life in about 1.1 billion years. The planet will be too hot to support life.

The Sun is a weakly variable star, and its actual luminosity therefore fluctuates. The major fluctuation is the eleven-year solar cycle (sunspot cycle) that causes a quasi-periodic variation of about ±0.1%. Other variations over the last 200–300 years are thought to be much smaller than this.
