<u>Answer:</u>
The major type of weathering that takes place in a desert in Physical Weathering.
<u>Explanation: </u>
Physical weathering also known as mechanical weathering takes place in deserts. This weathering takes place due to physical or mechanical forces. Frost chattering, temperature fluctuation also causes physical weathering.
In the desert, there is a fluctuation in temperature. In deserts, the temperature during the day will be very high and at night the temperature will be very low. As a result, the rocks expand during daytime due to heating and at night the rocks undergo contraction due to the reduction in temperature. Hence the rocks are weakened followed by the disintegration or breaking of rock.
Answer:
Blastocyst
Explanation:
As morula moves towards the uterine cavity by the end of the fourth day of fertilization, there is an increase in the number of its cells. Morula is transformed into a hollow ball of cells that has an internal cavity called blastocele, outer cells (trophoblast) and the inner cell mass.
This structure is called blastocyst which is present as a free structure in the uterine cavity for 2 days after which it becomes attached to the endometrium of the uterine wall. Attachment of blastocyst to the endometrium of the uterine wall is called implantation. The enzymes secreted by blastocysts make a burrow in the endometrium to facilitate implantation
Plants are producers and make their own food through a process of photosynthesis.
Organisms are classified into domains according to shared characteristics.
In this figure the answer is “all are correct”
Channel proteins are the green tubes, the bilayer is the grey circles with the lines attached, and the marker protein is the blue ball with the red carbohydrate chain attached
