Answer:

Chloroplast, mitochondrion

Explanation:

Photosynthesis occurs in the chloroplast, whereas cellular respiration occurs mainly in the mitochondrion.

Answer:

Mitochondria.

Explanation:

The Mitochondria is the powerhouse of the cell, meaning most processes that create energy (such as photosynthesis and respiration) occur in it.

Answer:

I think that the answer is non vascular plants

A chromosome consists of a single, double-stranded DNA molecule. Chromatids are two molecules of double-stranded DNA joined together in the center by a centromere. Chromosomes have a thin ribbon-like structure. Chromatids have a thin and long fibrous structure.

Answer:

As per Thomson’s model of an atom, the number of electrons (negatively charged) are

equal to the number of protons (positively charged) in an atom. Hence the +ve and –ve

charges are neutralized by each other that makes atom neutral as a whole.

Explanation:

Hope it's answer you plz mark as Brainlist

Answer:

Explanation:

Accorrding to Thomson's model of the atom, an atom consists of both negatively and positively charged particles. The negatively charged particles are embedded in the positively charged sphere.. Thus, by counterbalancing each other's effect, they make an atom neutral.

Answer: Atomos

Explanation: Matter is composed of indivisible building blocks. This idea was recorded as early as the fifth century BCE by Leucippus and Democritus. The Greeks called these particles atomos, meaning indivisible, and the modern word “atom” is derived from this term.

Answer:

     The mass (increasingly bigger size) of a tree comes from the soil. Which makes sense, right? After all, we are taught that plants need soil (enhanced “dirt”) to grow. According to Michigan State University Extension, problems typically arise when asked to explain why there isn’t a big hole around a tree. If the tree is using soil, then there must be less soil around it. But studies show virtually no difference in the amount of soil in a pot when a seed is planted from the amount of soil in the same pot when the plant from that seed is harvested. So where does the mass come from?

    The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun’s energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water. Yes, the carbon from carbon dioxide in the air we breathe out ends up in “food” molecules (called glucose) each of which contains 6 carbon atoms (and 12 hydrogen atoms and 6 oxygen atoms).

Explanation:

So the mass comes from the soil but its primarily carbon. HOPED THIS HELPED YOU!

Answer:

The model is inaccurate because the base pairs are incorrect.

Explanation:

The model of DNA that the student made was:

G-G

A-A

T-T

C-C

G-G

A-A

T-T

C-C

The model is pairing the bases incorrectly since guanine (G) forms a base pair with cytosine (C) and adenine (A) with thymine (T). In other words, the bases do not pair with the same type.

The DNA strands, which have deoxyribose, phosphate groups, and different bases, are together thanks to hydrogen bonds between the pairs. The pair G-C has three hydrogen bonds, while the pair A-T has two hydrogen bonds.

I think the answer is clouds.

Precipitation is any type of water that forms in the Earth's atmosphere and then drops onto the surface of the Earth. Water vapor, droplets of water suspended in the air, builds up in the Earth's atmosphere. Water vapor in the atmosphere is visible as clouds and fog.

answer:

Precipitation is most abundant where air rises, and least abundant where it sinks. It also tends to be greater near oceans and lakes, and in higher elevations.

the pea will be heterogeneous.

Explanation:

Answer: DNA, cytoplasm and cell membranes

Plants, animals, and bacteria have cytoplasm in common.

Plants are the autotrophic organisms. Animals are heterotrophic organisms. Bacteria are prokaryotes.

Plant cell, animal cell and bacterial cells have cytoplasm in common. DNA is also found in them and chloroplast is found in plant cell only. They help in the site of photosynthesis.

In Bacterial cell membrane bound organelles are absent such as Chloroplast, mitochondria and endoplasmic reticulum.

Cell membrane is also called plasma membrane is present in all plant and animal cell. DNA is a genetic material of the organism. In Higher organisms such as plants and animals DNA is a genetic material and in organisms like Bacteria RNA is present.

Therefore, Plants, animals, and bacteria have cytoplasm in common.

When a grain of pollen reaches the stigma, it creates a pollen tube for the sperm to journey down the style and fertilize the ovule; fertilized ovules become seeds. Fertilization is the death of the flower, as the petals drop or wither at this point and the ovary starts to enlarge and ripen into what we know as fruit

Answer and Explanation:

There are four phenotypes: tall, short, round, wrinkled

Let us say that for the high trait, tall dominates over short. For the shape trait, round dominates over wrinkled. This is:
