There are three types of joint mentioned here
Diarthrosis: it refers to the moving joints of the body, that is the synovial joints. These are more numerous in the members. In a synovial joint, the bones are associated through a cavity filled with a liquid called "synovium".

Amphiarthrosic joints: Articulation uniting two bone surfaces covered with cartilage, to which it allows only limited movements. Like symphysis of the vertebral column and syndesmosis of the ankle.

Synarthrosis: Term for a motionless joint where contact between bones occurs through a fibrous structure. Like Synostosis (Cranium), Suture (skull), Gomphosia (mouth), Synchondrosis (cartilage).

Which of the following mutations could lead to constitutive expression of the genes of the lac operon? View Available Hint(s) Wh
Molodets [167]

Options for part A are as follows:

A) A mutation in the operator sequence

B) A mutation in the lac-Z gene

C) A mutation in the lac-Y gene

D) A super repressor mutation

Answer:

The correct answer:

Part a - A mutation in the operator sequence

Part b - It ensures that a cell dedicates resources to the production of enzymes involved in lactose metabolism only when lactose is available in the environment

Part C. true.

Explanation:

part a:

If there is a mutation in the operator sequence leads to prevent binding of the repressor which leads to allowing constitutive expression of the genes various conditions.

part b:

The biological role of the lac operon makes sure that the cell dedicates resources to the production of enzymes involved in lactose metabolism only when lactose is available in the environment

Part c:

RNA polymerase cannot transcribe the structural genes due to the repressor binds to the lac operator, therefore, the proper function of the lac operon is possible when the placement of the operator sequence between the promotor and the structural genes.

Which of the following factors is needed during light-dependent reactions to create ATP and NADPH energy molecules?
Alexeev081 [22]

Answer: The correct answer is- Solar energy, carbon dioxide, and water.

Light dependent reactions comprise the first phase of photosynthesis (formation of food by green plants and algae in presence of sunlight) process.

This phase occurs in the thylakoid membrane of chloroplast.

During this phase, a green pigment chlorophyll absorbs energy from sunlight (in the presence of carbon dioxide and water) and convert it into chemical energy in the form of ATP and NADPH.

This energy is further utilized in the formation of food (glucose) in the next phase, which is a light independent phase of photosynthesis.

In photosynthesis, oxygen is produced by splitting of water molecule and it is released in the atmosphere.

Thus, solar energy, carbon dioxide, and water is the right answer.

Match the human activity with its effect on groundwater.
fgiga [73]

Answer:

3. Household wastes

2. Landfills

1. Agriculture

Explanation:

The groundwater is more and more contaminated, and there are numerous ways in which the contamination occurs. The causes of pollution mainly come from the human activities. The humans use all sorts of chemicals, fossil fuels, paints, and often there is waste from them, waste that is dumped into the drainage, and occasionally reaches the groundwater. The leaking of linings also manages to cause lot of damage, as very often it can reach the groundwater, causing heavily contamination of it. The agriculture, as much as it is needed, is a big polluter too, and the pollution mainly comes from the usage of pesticides, herbicides, and fungicides, which wash through the soil and end up in the groundwater.
