Answer:

Photosynthesis occurs in the chloroplast of the plant cell. Carbon dioxide, water, and the sun's energy are necessary for the chemical reactions of photosynthesis. The products of photosynthesis are glucose and oxygen.

Answer:

chloroplasts

Explanation:

in order to go through photosynthesis (which basically needs light) you need chloroplasts which are in the plant cell to catch that light and turn it into glucose (plants food)

Answer:

According to the diagram, what is occurring in step 7 is cytokinesis, with the separation of two daughter cells, following cell division.

Explanation:

Cytokinesis is a process that occurs at the end of mitosis or meiosis, being the final step of cell division. This mechanism allows the separation of the two daughter cells, with equal distribution of cytoplasm and formation of cell membrane, differentiating into two independent cells.

In the diagram it can be observed (step 7) that after the division process —in yellow— two arrows pointing to two cells are evident, which implies the process of cytokinesis.

Prior to the cytokinesis process, karyokinesis occurs, which is the separation of nuclei and formation of the nuclear membrane.

In animal cells, karyocinesis occurs by the effect of a ring of actin and myosin that helps to force the separation. In the plant cell, the fragmoplast is formed, a septum that induces the separation of the daughter cells.

The other options are not correct because:

Cell growth occurs in G1 phase.
Cell preparation occurs in interphase.
DNA replication occurs in S phase.
Mitosis is represented in yellow, and involves 4 phases.

A student measured the mass and volume of a metal sample using a triple beam balance and a graduated cylinder. The sample has a

alexdok [17]

Answer:

$d=3.79\ g/cm^3$

Explanation:

Given that,

The mass of a sample, m = 16.7 grams

Volume of the sample, V = 4.4 cm³

We need to find the density of the metal sample.

Density = mass/volume

Substituting all the values,

$d=\dfrac{16.7\ g}{4.4\ cm^3}\\\\=3.79\ g/cm^3$

So, the density of the metal sample is $3.79\ g/cm^3$ .

What do surface current affect !!!!

amid [387]

Answer:

Surface currents affect climate by moving cold and warm water around the globe. In general, currents carry warm water from the tropics toward the poles and bring cold water back toward the equator. A surface current warms or cools the air above it, influencing the climate of the land near the coast.
