The plants in a specific environment be impacted if there was a sudden drop in the amount of bacteria present in that area, there are positive and negative consequences associated with this situation.

Positive:

The decrease in bacterial colonization will prevent the plant from the diseases caused by the bacteria and this will promote plant growth. Like, black rot in Brassica caused by Xanthomonas campestris, bacterial canker in tomato, capsicum and chilli caused by Clavibacter michiganesis.

Negative:

Plants remains in symbiotic relationship with bacteria in order to obtain impermeable inorganic minerals from the soil. In the absence of bacteria, the plants will not receive these nutrients, and their growth may be hampered. Example bacteria fixes atmospheric nitrogen which is taken up by the root nodules of leguminous plants. In return these bacteria gets the food like carbohydrates produce by the plants

Match each structure on the left with the corresponding function on the right. Group of answer choices Chemically digests food,

Ad libitum [116K]

Answer:

1. Chemically digests food, absorbs nutrients and minerals from food - Small intestine

2. Breaks down and physically digests food - Stomach

3. Metabolizes nutrients, detoxifies blood, makes bile - Liver

4. Stores and concentrates bile - Gallbladder

5. Removes waste products and excess fluid - Kidney

6. Filtering structure of kidney - Nephron

7. Produces eggs and reproductive hormones - Ovary

8. Produces sperm and reproductive hormone - Testis

Explanation:

This question is asking to correctly match certain digestive organs with their respective function. The organs and their function are as follows:

- Small intestine: Small intestine is the major organ that digests food chemically, and also absorbs nutrients and minerals from food.

- Stomach: This breaks down and physically digests food.

- Liver is responsible for metabolizing nutrients, detoxification of blood, and making of bile.

- Gall bladder is a greenish yellow organ responsible for the storage and concentration of the bile produced by the liver.

- Kidney is the major excretory organ of the body, which removes waste products and excess fluid from the body.

- Nephrons are numerous filtering structure of the kidney.

- Ovary is the female reproductive organ that produces the eggs/ova and other reproductive hormone like oestrogen.

- Testis is the male reproductive organ that produces the sperm and other reproductive hormone like testosterone etc.

The angle of Earth's tilt has changed throughout Earth's history and is still changing today. If Earth's tilt were to decrease

olganol [36]

Answer:

The world climate would drastically change.

Explanation:

First off, both poles would have rapid expansion, with the freezing of more water near the poles.
Many species of trees and plants would die out in certain areas, since they tend to be in their ideal locations, so the change in climate will make the northern parts of many habitats destroyed.
Deserts would expand and the average temperature would rise.
Also, many animals would also die out, because of the change in their environments.
Conifers would shift southward, causing many forests / parts of forests to turn into wastelands, causing the earth's oxygen production to decrease.

The production of egg and sperm cells follows a certain sequence of events.

Maru [420]

The production of egg and sperm cells follows a certain sequence of events.

The correct order of those events are:
MEIOSIS, CELL DIFFERENTIATION, MATURE GAMETES.

Meiosis is defined as the process wherein a single cell is divided twice to produce four cells that contains half the original amount of genetic information.

Cell differentiation is defined as the process wherein the less specialized cell becomes a more specialized cell. The haploid cells are the end result of meiosis. They must undergo cell differentiation before they can become mature gametes.
