What was one model of the solar system developed by early astronomers?

Answers

One of the most famous early models was the geocentric solar system. It was a solar system where Earth was the center of the system since people believed it to be so. We of course nowadays know that's untrue.

What happen when a cell divides?

Answers

When a cell divides it makes two whole new cells this process is called mitosis.

When a cell divides into 2 then that means that you are growing and a cell breaking into two is called mitosis.

Sweating and panting are examples of which characteristic of life?a. responding to the environment
b. using energy
c. reproducing
d. growing and developing

Answers

The correct answer is option a. responding to the environment.

The sweating is the release of sweat from the sweat glands. The sweating releases the water molecules on the skin surface as a result of increased body temperature due to changes in atmospheric temperature. The water molecule from the skin evaporates causing a decrease in body temperature.

The panting increase in the heat loss by respiration, hence, it is also a respond to the increased atmospheric temperature. So, both the conditions are associated with the temperature increase outside the body, here change in temperature act as stimuli and body react according to change.

A: responding to the environment

Explanation:

Explain the connection between the oxidation of water in photosystem II of the light-dependent reactions and the synthesis of glyceraldehyde-3-phosphate in the light-independent reactions.

Answers

Answer:

Please find the explanation below

Explanation:

This question is describing the processes involved in photosynthesis. In the light-dependent stage of photosynthesis, specifically photosystem II (PSII), water is oxidized in a process called PHOTOLYSIS OF WATER. This process produces electrons and Hydrogen ions (H+). The electrons produced via this process is accepted by NAD+ to yield NADH.

The NADH is an electron carrier produced during the light-dependent stage and used to reduce 3-phsophoglycerate (PGA) produced in the light-independent stage to glyceraldehyde-3-phosphate (G3P).

Final answer:

The oxidation of water in photosystem II of the light-dependent reactions is connected to the synthesis of glyceraldehyde-3-phosphate in the light-independent reactions.

Explanation:

In photosynthesis, the oxidation of water in photosystem II of the light-dependent reactions is connected to the synthesis of glyceraldehyde-3-phosphate in the light-independent reactions. In the light-dependent reactions, photons of light strike photosystem II and excite electrons, which then pass through an electron transport chain, leading to the production of ATP and NADPH. The ATP and NADPH generated in the light-dependent reactions are then used in the Calvin cycle to power the synthesis of glyceraldehyde-3-phosphate from CO₂.
