F an adult dog has 78 chromosomes, the number of chromosomes in a dog’s sperm cell will be

1 answer:

6 0

There's 39 chromosomes in the sperm cell. Why? Because sperm cells are gametes and therefore they are haploid cells meaning they have half the number of chromosomes of a regular cell or diploid cell.

78 / 2 = 39

Imagine a diploid organism that has 6 pairs of homologous chromosomes in their somatic cells. Given

stich3 [128]

Answer:

A. False

B. False.

C. True.

D. False.

E. True

F. True

G. True

H. False.

Explanation:

Diploid organism has almost double the cells than in the Haploid. The number of chromosomes in each diploid cell are also nearly twice the other cells. Diploid is any cell or organism which has two sets of chromosomes. Gamete is considered as the sex cell. It has ability to pair up and formulate the reproductive cells.

A bat species (species 1) lives in a city. Another bat species (species 2) established a population in that same city after some

ddd [48]

Answer:

Roosting areas in buildings of any height are the resource partitioning of both bat species.

Explanation:

The fundamental niche refers only to physic conditions in which a species can live and survive in the absence of any interaction with other species.

The realized niche refers to the restricted conditions in which a species can live and survive as a result of environment physic characteristics and the interaction with other species.

Competitive exclusion refers to the exclusion of the inferior competitor by the superior competitor when there is not habitat differentiation, and both species can not share the same niche. In this case, the effective niche of the dominant species completely occupies the fundamental niche of the inferior competitor.

Resources partitioning refers to one dominant species monopolizing the resources, and the other inferior species use resources -partially or completely-, migrates or get extinguished.

A way in which species can divide resources is by living in different habitat areas. These species might eat the same food, and can roost in different places within the same habitat. This resource partitioning and differentiation in the function of their physic location allows both species to coexist more effectively.

In the present example, both bat species can coexist in the same city but the weaker bat species (species 1) roost at the top of the shorter buildings while dominant species (species 2) roost at the top of the highest buildings.

2. What procedure did you use to complete the lab? Outline the steps of the procedure in full sentences. Virtual Lab: Water Eros

Anettt [7]

The procedures that can be used to perform water erosion laboratory practicals are:

The use of detachment
Transportation
Deposition.

<h3>What is Water Erosion?</h3>

This refers to the biological process where rock particles are broken down into smaller particles and how they are removed by water.

Hence, we can see that in a laboratory experiment, one would need different apparatus such as:

Pitchers
Bottles
Soil
Water, etc.

This would be used to test the loss of water as it is put into the soil from the set of bottles to see how much the water is retained.
