Answer:
Four reactions that occur in kreb cycle transfer electrons from substrate to an electron accepting enzyme.
Explanation:
There is four such a response in which electron is transported from substrate to electron-allowing enzyme. In three of those, NAD+ is decreased to NADH and in one FAD decreases to FADH2. The TCA cycle is likewise recognized as the Krebs cycle after the signature of English biochemist Hans Kreb who illustrated the pathway in the 1930s.

How do the homologous chromosomes compare to each other ?
Answer:
The two chromosomes in a homologous pair are very similar to one another and have the same size and shape. Most importantly, they carry the same type of genetic information: that is, they have the same genes in the same locations.
Explanation:
2. The text explains that selective breeding involves breeding animals or plants for
specific desirable traits. For example, humans bred different types of dogs to
accomplish certain jobs. Farmers breed chickens for having more meat and laying a
greater amount of eggs. Cattle are often selectively bred either for more meat or for
more milk production. The text also notes that breeding animals for size and strength
interferes with natural animal processes.
Based on this information presented in the text, who benefits from the traits different
animals are bred for?
A. humans breeding the animals
B. the animals being bred by the humans
C. both the humans breeding the animals and the animals being bred by the humans
D. animals not being bred by humans
Answer:
A. the humans breeding the animals
Explanation:
It says in there that it interferes with the natural animal processes so it probably doesn't help the animal, and it also said in there that we have breed for more desirable traits in other words we bred them to be more useful to us and give us benefits.

3. Which feature is commonly formed
at a plate boundary where oceanic
crust converges with continental crust?
(1) a mid ocean ridge (2) an ocean trench (3) a transform fault (4) new oceanic crust
Answer:
2) an ocean trench
Explanation:
Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.
What is Ocean Trench?Long, narrow depressions on the seafloor are known as ocean trenches. These chasms are among the deepest natural places on Earth and the deepest portions of the ocean.
Every ocean basin on the planet has ocean trenches, but the deepest ones encircle the Pacific Ocean as part of the so-called "Ring of Fire," which is also home to active volcanoes and earthquake-prone regions. Tectonic activity, which refers to the movement of the Earth's lithosphere, is what causes ocean trenches.
Ocean trenches in particular are a characteristic of convergent plate borders, which occur where two or more tectonic plates collide. In a process known as subduction, dense lithosphere melts or slides beneath less dense lithosphere along numerous convergent plate borders, forming a trench.
Therefore, Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.

Answer:
Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. It occurs in ovary of female flower
Explanation:
After pollen grains land on the stigma, a pollen tube grows from the pollen grain, through the style, and into the ovary. Sperm cells inside the pollen grain travel down the pollen tube and into the ovary which contains the ovules.

What happens during the 4 stages of mitosis
Answer:
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope ...
Explanation:
Brainliest plz trying to level up1. Consider the following food chain.
grass
deer
wolf
If the deer population increases, explain what could happen to the grass population
Most likely the grass population will decrease and the wolf population will increase.
Eventually it should level out again though.
If the population of deer will increase will result in the decrease in grass quantity.
What is a food chain?A food chain is a linear network of links in a food web that begins with producer organisms and ends with an predator, detritivores, or decomposer species.
A food chain also shows how organisms are related to one another through the food they consume. Each extent of a food chain represents a distinct trophic level.
Overgrazing occurs when there are too many deer in a given area, resulting in the loss of brush and shrubs in forested areas. The absence of undergrowth means that small animals and birds have no place to shelter and nest.
As a result, many native species are becoming extinct because they no longer have access to the habitat they require.
Thus, the grass population will decrease as a result of increase in deer population.

Calculate the number of liters of liquid that are in Lake Erie, which has a volume of 484 cubic km (km3). Express your answer in scientific notation.
Answer: The answer in scientific notation is [tex]4.84\times 10^{14}[/tex]
Explanation:
The conversion factor is : [tex]1km^3=10^{12}L[/tex]
Given : Volume of liquid in Lake Erie = [tex]484km^3[/tex]
To find : Volume of liquid in Lake Erie in units of liters
As [tex]1km^3=10^{12}L[/tex]
Thus [tex]484km^3=\frac{10^{12}}{1}\times 484=484\times 10^{12}L[/tex]

Explanation:
One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water. Water will penetrate the seed coat and cause the embryos inside to plump up. Don't soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.
