The two major cell organelles involved in energy transformation are mitochondria and chloroplasts. Thus option A is correct.
what is function of chloroplast ?Chloroplasts are the cellular organelle found in photosynthetic organism like plants and algae.
They are present in mesophyll cells of leaves and contain a high concentration of chlorophyll which absorb sunlight; It is absent in animal cell.
Chloroplast has extra-nuclear DNA and are semiautonomous.
They synthesize food by the process of photosynthesis by absorbing sunlight into chemical energy.
It is major production house of NADPH and molecular oxygen (O2) by photolysis of water; It produces ATP from photosynthesis.
It also indirectly involve in generation of carbon and sugar molecule during the Calvin Cycle or dark reaction of photosynthesis.
Thus option A is correct.

Explanation:
sorry if i keep answering ur questions im j good at this stuff lol
Answer:
D.
Explanation:
Stem cells differ from other kinds of cells in the body. All stem cells—regardless of their source—have three general properties: they are capable of dividing and renewing themselves for long periods; they are unspecialized; and they can give rise to specialized cell types. Stem cells are unspecialized.

Raj drinks a glass of water in his kitchen. The water is at room temperature, and Raj decides to make it colder by adding ice. Which of the following describes why the ice cubes will melt?
Answer:
Heat from the water moves into the ice.
Explanation:
The ice has more heat than the frozen ice cube, so it will melt it.
In eukaryotes, all the reactions of photosynthesis occur in various membranes and compartments of the chloroplast.
a. True
b. False
Answer:
The correct answer is - a. true.
Explanation:
The chloroplast is surrounded by inner and outer membranes. These membranes help in separating the inner compartments and structures from the cytosol Inside the chloroplast. These various membranes and compartments play various roles during photosynthesis.
For instance;
a) stroma- the Calvin cycle takes place in the stroma
b) thylakoid membrane - the light reactions takes place here
c) envelope membranes- the inner and outer membranes of the chloroplast
The blood vessels that have the smallest diameter and consist of a single layer of simple squamous epithelial
cells so they may facilitate the exchange of substances are
Answer:
Capillaries
Explanation:
Capillaries are one of the three major blood vessels in humans (the other two being; veins and arteries). They are known to connect the arteries and the veins together in the circulatory system. Capillaries majorly function in the exchange of substances e.g oxygen, nutrients between the blood and tissues.
Due to their role in exchanging substances via diffusion, capillaries contain the simple squamous type of epithelial tissue, which helps them perform this function. Furthermore, capillaries are the smallest in diameter and most abundant in number of all blood vessels.
Haley knows that plants and animals are made up of many different materials. She wants to know how these materials can cycle through an ecosystem.
What question could Haley ask to learn more about this topic?

What happens to the materials that make up a living organism after it dies?
C.
What will happen to a sunflower plant if it is grown in a dark closet?
D.
What kind of plant should Haley buy her mom for her birthday
Answer:
B. What happens to the materials that make up a living organism after it dies.
Explanation:
An ecosystem can be defined as the natural living habitats of both living and non-living organisms.
Ecosystem services such as plant pollination, nutrient cycling and water purification are essential services that are being provided by the ecosystem. These services are really very vital, important and useful for the sustenance of life, both for humans, plants and animals because they enhance social welfare.
In this scenario, Haley knows that plants and animals are made up of many different materials. She wants to know how these materials can cycle through an ecosystem. Therefore, the question Haley could ask to learn more about this topic is; what happens to the materials that make up a living organism after it dies?
Basically, the material that make up a living organism decomposes after it dies and are then used up as nutrients by plants growing on the soil.

where does pyruvate as intermediate take place in photosynthesis? plz explain also thanks
Answer:
Pyruvate take place after the process of glycolysis.
Explanation:
Pyruvate as intermediate take place in the process of photosynthesis after glycolysis process. One glucose molecule is converted into two molecules of pyruvate. This pyruvate molecule then converted into acetyl CoA, which is a two-carbon molecule. A molecule of coenzyme A is a very important reactant for this reaction, which produces a molecule of carbon dioxide and reduces a NAD+ to NADH.

Select all that apply.
A
Peas were the only thing available at the monastery.
B
Pea plants grow fast.
C
Pea plants are easy to grow.
D
Pea plants have several distinct traits that vary.
Answer:
I think option B and C is correct answer
Mendel used pea plants as they were easy to grow and exhibit several distinct traits that vary.
Mendel's ExperimentMendel's experiment was accomplished with the help of Pisum sativum, that is, the garden pea to study inheritance.
Mendel chose pea plants as they are easy to grow.
They also possess many visible features, which may vary.
These features comprise seed color, seed form, flower color, pod color and form, placement of flowers and pods on the stems, and length of the stem. Each of the feature has two common values.
Thus, the correct answers are options C and D.

igneous rock determined 25 million year old plate movement transported 100,000 meters. How fast is plate moving?
Answer:
0.004 m/yr.
Explanation:
Hello!
In this case, since the velocity of any object is computed by dividing the travelled distance by the elapsed time, we obtain:
[tex]V=\frac{distance}{time}\\\\V=\frac{100,000m}{25,000,000yr}\\\\V=0.004m/yr[/tex]
It means that the plate moves 0.004 m every year.

7) Rank the following milk samples from most expected bacterial growth to least: Be sure to explain your rankings. (0.5 points) a. Pasteurized milk stored at 4*C for one week b. Pasteurized milk stored at room temperature for 4 days c. Autoclaved milk
Answer:
b. Pasteurized milk stored at room temperature for 4 days
a. Pasteurized milk stored at 4*C for one week
c. Autoclaved milk
Explanation:
Autoclaved milk has least expected bacterial growth because Autoclaved sterilization kills all the bacteria present in it so little chance of bacterial growth. Pasteurized milk stored at room temperature for 4 days has more bacterial growth due to favorable environment whereas little growth occur in the Pasteurized milk which stored at 4*C for one week due to less favorable environment.

1. Discuss how the study of fossils provides strong evidence for evolution. (13.2 and 13.3)
Answer:
in fossils we see homologous structures that suggest a common ancestor.
By looking at the bones of the arms and comparative anatomy we see the similar structure and function that is retained.
When looking at other animals like birds we see Analogous structures that look similar but have a different function (flying).
Finally we see Vestigial structures which are structure that no longer function as they once were used for. An example of this is the coccyx (tail bone in humans) compared to tails in dogs, cats, monkeys, etc.

Answer:
Vary in height primarily because of the degree of various stressors on each population
Explanation:
Shorter plants became taller because of the various stressors such as unavailability of sunlight. Due to unavailability of sunlight, the plants grow taller for gaining solar radiation that is required for the process of photosynthesis. So we can say that the environmental condition or stress brought changes in the plant body.
