Answer:
Lower gravitational force due to lower mass.
Explanation:
Mars has lower gravitational force than Earth because of its lower size because mass has a direct effect on gravitational force of an object. Earth has mass of 5.972 × 10^24 kg which is 10 times greater than mass of Mars which is 6.4171 x 10^23 kg. So due to earth's more mass, it has more gravitational force than planet Mars which has lower mass than earth.
Among the following the benefit of using agroforestry in a tropical rain-forest climate is that growing trees provides a boost in crop output for a short time.
Answer: Option A
<u>Explanation:</u>
Agroforestry is a kind of practice in which trees are grown along with the crop which benefits the crop; there is different alley cropping, silvopasture and forest cropping.
Combining forests and agriculture seem to perform many benefits to the farmer. This type of practice has enabled farmers to show nutrient cycling, crop productivity and change in the micro climate of the place.
Answer:
ribosome, cell membrane, nucleus
Explanation:
The organelles that perform similar functions in both plant and animal cells among the listed organelles would be <u>the ribosome</u>, <u>the cell membrane</u>, and <u>the nucleus.</u>
First of all, chloroplast and cell wall are limited to the plant cell only. Animal cells do not have these organelles.
The ribosome functions as the site of protein synthesis in both plant and animal cells. The cell membrane acts as a channel for the control of the movement of materials in and out of the cells and is found in both plant and animal cells. The nucleus is also present in both cells and serves as the control unit of the cell by housing the genetic materials and dictating how the cells will behave.
Answer:
The correct option is option "B"
Explanation:
pathogenic cells
Answer:
The possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az
Explanation:
The genotype of F1 progeny is AaZz
The allele pair of gametes would contain one allele for characteristic represented by "A or a" and other allele for characteristic represented by Z or z"
Thus, total four allele pairs will be formed.
First allele pair would be - AZ
Second allele pair would be - Az
Third allele pair would be - aZ
Fourth allele pair would be - az
Hence, the possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az
