D. The planet's orbital path will become smaller and its orbital period will increase.

The more gravity an object has, the more it will pull objects.

Answer:

The correct answer will be option D.

Explanation:

Planets orbit around the Sun (star) due to the gravity of this star which pulls down them around it. This gravity is the vital force which maintains the elliptical path of their orbit.

If this force of gravity will change it will affect the celestial bodies revolving around it like a planet as this force of gravity is directly proportional to mass and inversely proportional to the distance between them.

According to the question if the gravity of the star increases it will change the orbital path of the planets as they will be more pulled towards the sun which will decrease the distance between the star and planet and the orbital path will become smaller and the orbital period will increase.

Thus, option D is the correct answer.

Controlling blood glucose levels in the animation, you saw that both high blood glucose levels and low blood glucose levels are
r-ruslan [8.4K]
There are 2 main hormones that can control blood glucose levels : insulin and glucagon.
Both of them are produced in the pancreas.
If the blood glucose level is too high, insulin can help by converting glucose into glycogen, the storage form of carbohydrates.
If the blood glucose is too low, glucagon can covert glycogen back into glucose to increase blood glucose level. Both of these hormones can work together to control blood glucose level in body.

1) Ecology is the scientific study of the distribution and abundance of organisms, the interaction among organisms, and the interactions between organisms and their abiotic environment. Ecologists try to understand the inner workings of natural ecosystems and the species they contain.

2) Ecosystems have no particular size. An ecosystem can be as large as a desert or a lake or as small as a tree or a puddle. If you have a terrarium, that is an artificial ecosystem. The water, water temperature, plants, animals, air, light and soil all work together.

3) The biotic factors of an ecosystem include all the populations in a habitat, such as all the species of plants, animals, and fungi, as well as all the micro-organisms. Also recall that the nonliving factors are called abiotic factors. Abiotic factors include temperature, water, soil, and air.

4) For aquatic ecosystems, these factors include light levels, water flow rate, temperature, dissolved oxygen, acidity (pH), salinity and depth.


Hope this helped. ;)

Why do we breathe oxygen? how do we get energy out of our food?
lapo4ka [179]
We breath oxygen because it is needed to burn fuel [ sugars and fatty acids] in our cells to produce energy. Oxygen is also brought into the lungs via breathing; where it is transported by red blood cells to the entire body to be used to produce energy. The food we eat gives us protein, sugars, vitamins etc. for energy
