7. Indicate which stage of mitosis is occurring in each of the images above and describe what is
happening using the words: chromosomes, centrioles, nucleus, and spindle fibers.
A
B
D
C

Answer:

allows blood to flow between the two atria

allows blood to flow from the atria to the ventricle

prevents blood from flowing into the atria when ventricle pumps

allows blood to flow between the two ventricles

prevents blood from flowing into the atria when ventricle pumps

The valves allow the blood to flow in only one direction so for example when the left ventricle contracts the mitral valve prevents the blood from going back into the left atrium.

Answer:

B. An idea supported by evidence.

Answer:

Protons flow from the thylakoid space into the stroma of the chloroplast

Explanation:

Chemiosmosis is one of the two events that occur in oxidative phosphorylation (the other being electron transport chain). Chemiosmosis, which occurs to synthesize ATP in both cellular respiration and photosynthesis, is the process whereby protons (H+) move across a membrane via osmosis. In other words, chemiosmosis builds the proton gradient required to power ATP synthesis via the aid of an enzyme called ATP synthase.

In cellular respiration, chemiosmosis occurs when protons flow from the intermembrane space into the matrix while in PHOTOSYNTHESIS, cheniosmosis occurs when protons flow from the thylakoid space into the stroma of the chloroplast.

The flow of protons takes place from the thylakoid space into the stroma of the chloroplast during the chemiosmosis in chloroplasts.

It is one of the events, which takes place during oxidative phosphorylation. It generally takes place to produce ATP in both the process of photosynthesis and cellular respiration. In the process, the protons move across a membrane through osmosis.

It can also be stated that building of the proton gradient for the synthesis of ATP takes place by chemiosmosis with the help of an enzyme known as ATP synthase.

Chemiosmosis takes place when flow of protons takes place from the intermembrane space into the matrix during cellular respiration. While in photosynthesis, chemiosmosis takes place when flow of protons takes place to the stroma of the chloroplast from the thylakoid space.

Thus, in chloroplasts, chemiosmosis takes place when flow of protons takes place from the thylakoid space into the stroma.

Answer:

by experimental repeatability, which enables to demonstrate the accuracy and reliability of the scientific study.

Explanation:

Scientific ideas and theories are used to explain observations and phenomena from the real world. Scientific validation comes by acceptance of the scientific community, which is generally achieved by scientific publications in well-reputed peer-reviewed journals. In order to be validated, these explanations must be repeatedly tested by using the scientific method, thereby proving the effectiveness of the proposed research method used to obtain information.

Answer:

A. alternation of generations

Explanation:

Basically, a plant's life cycle has two main parts, namely a diploid and a haploid phase. Since the plant alternates between these two phases in its life cycle, the alternation is typically called the alternation of generations.

Hope this helped!

A. alternation of generations

Alternation of generations (also known as metagenesis) is the type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that have distinct haploid sexual and diploid asexual stages.

Answer:

1. ATP

2. ADP

Explanation:

Thus, ATP is the higher energy form (the recharged battery) while ADP is the lower energy form (the used battery). When the terminal (third) phosphate is cut loose, ATP becomes ADP (Adenosine diphosphate; di= two), and the stored energy is released for some biological process to utilize.

Explanation:

A pyroclastic flow is a dense, fast-moving flow of solidified lava pieces, volcanic ash, and hot gases. It occurs as part of certain volcanic eruptions. A pyroclastic flow is extremely hot, burning anything in its path. It may move at speeds as high as 200 m/s. Pyroclastic flows form in various ways.

Yeah yeah so :D,

Large polar molecules can only cross the membrane with the help of protein named channel protein and carrier protein.

So, this both proteins act like a gate, the large molecules enter the protein and the protein let the large molecules in to the membrane. (see the picture so that you can understand more, its carrier protein)

the only difference between channel protein and carrier protein is, channel proteins has fixed shape while carrier protein can flip.

Large or polar molecules like glucose can't pass through the phospholipid bilayer. Smaller molecules usually diffuse freely for example water and CO2.

Large molecules like glucose diffuse through channels. This is a form of passive transport.  Carrier proteins are involved.

What color light is best absorbed by chlorophyll?

As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.

Explanation:

therefore it is blue

Answer:

Chlorophyll a: This is the most abundant pigment in plants. Chlorophyll a absorbs light with wavelengths of 430nm(blue) and 662nm(red). It reflects green light strongly so it appears green to us.

Explanation:

So in conclusion the answer will be Blue <3 Hope this helps!

Answer:

The correct answer is - 30.25%

Explanation:

Allele frequency in a population is the number of a particular allele in the population divided by the total number of all alleles present in the population for the particular gene.

The population has the allele frequency or q = 0 .55

So, the percentage of the white spots moth in this moth population would be -

q^2 = (0.55)^2

q^2 = 0.3025

q^2 = 0.0325 *100

= 30.25 %
