50 people because the widow's peak is dominant. Those who don't have a widow's peak do not have the gene.

If the gene for the hair pattern "widow's peak" is dominant, it means that individuals with at least one dominant allele will express the trait. We would expect 50 people to be heterozygous (Ww) for the widow's peak trait.

Heterozygous refers to a genetic condition in which an individual possesses two different alleles for a specific gene. Alleles are alternate forms of a gene that can code for different variations of a particular trait. In a heterozygous individual, one allele is dominant and the other is recessive.

The dominant allele is expressed in the phenotype, meaning it determines the physical appearance or characteristic, while the recessive allele remains hidden and does not show in the individual's observable traits. The notation for a heterozygous trait is typically represented by two different letters, one for each allele (e.g., Aa).

Assuming that "W" represents the dominant allele for widow's peak, and "w" represents the recessive allele.

Given that 50 people in the population have a widow's peak (homozygous dominant, WW), we can deduce that the other 50 people must have the genotype for heterozygous (Ww) to express the trait.

Answer:

d) habitat loss

Answer: Light is a form of electromagnetic radiation. Other forms of electromagnetic radiation include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays, and gamma rays. The only difference between them is their wavelength, which is directly related to the amount of energy the waves carry. Scientists classify them by the frequency of their wavelength, going from high to low frequency. When a wave has a lot of energy, it could be a gamma ray or x-ray. If it has low frequency, it has less energy and could be a TV or radio wave.

That is because your heat slowly devolves into chemicals that trees use for oxygen. And if there is no trees around it can take 100's of miles until it gets to trees.

Answer:

The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The sun, earth, and other bodies radiate electromagnetic energy of varying wavelengths. Electromagnetic energy passes through space at the speed of light in the form of sinusoidal waves.

Answer:

have a nucleus - Eukaryotic

contain cytoplasm - Both

comprise most multi-celled organisms - Eukaryotic

mostly single-celled organisms - Prokaryotic

have membrane-bound organelles - Eukaryotic

are the smallest unit of living matter - Both

are produced by division of another cell - Both

contain DNA - Both

Explanation:

1. Eukaryotic cells are cells that possess a membrane-bound nucleus that houses their genetic material.

2. Both eukaryotic and prokaryotic cells have a cytoplasm, which is the gelatinous substance where all other organelles and substances are found.

3. Most multicellular organisms comprises of eukaryotic cells.

4. On the other hand, most single celled organism, are Prokaryotic.

5. Eukaryotic cells, in addition to the possession of a membrane-bound nucleus, they also possess membrane-bound organelles e.g mitochondria, endoplasm reticulum.

6. Cells, generally, are the smallest unit of living matter. This comprises of both eukaryotic and prokaryotic cells.

7. Likewise, all cells arose from already preexisting cells according to the cell theory. Therefore, both eukaryotic and prokaryotic cells are made by the division of another cell.

8. Both prokaryotic and eukaryotic cells have a genetic material like DNA where they store genetic information.

The cell wall is a layer outside the cell membrane and provides rigid support and protection to the cell. So, the correct option is A.

A cell wall is a thick and rigid layer composed mainly of polysaccharides present outside of the cell membrane that protects the cell. A cell wall is a part of a cell but it is not a living component. Unlike the cell membrane, a cell wall is totally permeable in nature.

The cell wall of different kinds is present in plants, fungi and prokaryotes. Animal cells do not have a cell wall.

The cell wall in fungi is made up of a polysaccharide called chitin. This component is also present in the exoskeletons of arthropods.

The cell wall in the case of prokaryotes is made of a polysaccharide called peptidoglycan. Prokaryotes have 2 layers in their cell wall.

Plants contain cell walls made of cellulose. The plant cell wall has 3 layers. These are pectin, cellulose and hemicellulose. It also contains a small number of minerals.

The materials required for the formation of the cell wall are a special kind of polysaccharide called structural polysaccharides. The monomer for these polysaccharides is glucose.

Therefore, the correct option is A.

A) The gene flow between hatchery-reared and wild populations is leading to a decline in fitness of wild populations.

Explanation:

we have relative fitness at its greatest in trouts whose parents are wild x wild. crossing the wild with hatchery reared causes a decrease in the fitness of the troutgene flow is the exchange of genes between two different breeds. the wild is a greatly diverse breed and it is highly adaptive. while the hatchery reared is less adaptive.when these two breed less fit alleles will then be transferred to the wild

The addition of a water molecule breaks a covalent bond between sugar monomers

Explanation:

The digestion of carbohydrates by enzymes is an example of a hydrolysis reaction.

Carbohydrates are chains of monosaccharides. Hydrolysis involves the addition of a water molecule that cleaves the covalent bond between the molecules of sugar.

The reverse reaction is a condensation reaction, the joining of sugar monomers to create a carbohydrate releases a molecule of water.
