How can using a dam as a source of freshwater also harm wildlife?
A. Dams help control floodwaters.
B. Dams provide drinking water.
C. Dams displace existing habitats.
Ο Ο
D. Dams provide water recreation.

Answers

Answer:

c

Explanation:

because its the only one that would be hurting wild life.

Using a dam as a source of freshwater can harm wildlife by displacing existing habitats. Therefore, option (C) is correct.

What are the negative impacts of dams?

Dams often require the creation of reservoirs, which can submerge large areas of land and alter the natural flow of rivers and streams. This can lead to the loss of important habitats for fish, mammals, and other wildlife that rely on rivers and streams for food, shelter, and reproduction.

In addition, changes in water temperature, dissolved oxygen levels, and water flow can negatively impact aquatic ecosystems downstream from the dam.

These impacts can be mitigated through careful planning and management, such as the creation of fish ladders and other structures to help fish navigate past the dam, and the release of water at appropriate times to mimic natural flow patterns.

How does a branching tree diagram show evolutionary relationships?

Answers

Answer:

A phylogenetic tree (also phylogeny or evolutionary tree) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics.

In wolves, gray coat color (G) is dominant to black (g) and brown eyes (B) are dominant to blue (b). The genes that control these traits are located on different chromosomes. The alpha male of the pack has the dominant phenotype for both traits and is heterozygous for both traits. The alpha female has brown eyes and a black coat; she is heterozygous for eye color. Which option represents gametes that would be made by the alpha female

Answers

The combination of gametes that will be produced by the Alpha female is Bg, Bg, bg and bg.

According to this question, two genes coding for eye color and coat color in wolves are involved. Gray coat color (G) is dominant to black coat color (g) while brown eyes (B) are dominant to blue eyes (b).

The alpha female of the pack is said to have a brown eyes and a black coat (gg) but she is heterozygous for eye color (Bb). This means that she posseses the following genotype: Bbgg.

According to Mendel in his law of independent assortment, alleles of a gene will segregate into gametes independently of one another.

This means that the alpha female with genotype (Bbgg) will segregate into the following combinations of gametes: Bg, Bg, bg and bg.

HELP ME MAKE THIS ESSAY BETTERStructure and Function of MicroscopesA microscope is a laboratory instrument used to examine objects that are too small to be seen by the naked eye. There are several types of microscopes but in this essay, we will be discussing the compound light microscope, the transmission electron microscope, and the scanning electron microscope. And we will be comparing its structure and function.From its name compound light microscope uses light as its radiation source with a wavelength that reaches from 400 to 700 nm though the Transmission electron microscope uses electrons as its radiation source, the scanning electron microscope uses electrons as well which wavelength reaches 0.005 nm.For the lens, the compound light microscope uses glass that is have its maximum resolution of 200 nm and can view colored images with an eyepiece powered 10x and 3 or 4 objective lenses that are power can be (4x, 10x, 40x) power. both transmission electron microscope and scanning electron microscope uses Electromagnetic as their lens although transmission electron microscope lens maximum resolution is 1 nm, and its maximum magnification power is 250 000x with a monogram view and scanning electron microscope lens maximum resolution is 10 nm and its maximum magnification power is 100 000x with a monogram view as well.For the specimen, the compound light microscope supports both living and non-living specimens. The transmission electron microscope and the scanning electron microscope both support only non-living specimens although the transmission electron microscope supports it on a small copper grid in a vacuum, and the scanning electron microscope supports it on in a metal disc in a vacuum.In the end, all microscopes are useful without microscopes no medicines would be found because scientists would not know how to treat the micro viruses and bacteria, and we could not explore and discover micro-organisms around us that we cannot see with our naked eye.

What are lipids?

Lipids have three main biological activities in the body: they are essential signaling molecules, structural elements of cell membranes, and energy storage facilities.

Triacylglycerols (commonly known as triglycerides), phospholipids, and sterols are the three primary categories of lipids. Fats are subtypes of lipids that are typically composed of glycerol and fatty acid chains.

One sort of lipid, which includes fats, is a group of molecules that don't mix well with water. Hydrophobic, nonpolar, and primarily composed of hydrocarbon chains, lipids have a tendency to be.
