The climate along the 30° latitude north and south is

In humans, the allele for dimples (D) is dominant to the allele for no dimples (d). At another gene locus, the allele for broad

Inga [223]

Answer:

Explanation:

As given, Allele for dimples(D) is dominant over alleles for no dimples (d), so D is dominant over d.

Allele for broad eyebrows (B) is dominant over allele for slender eyebrows (b), so B is dominant over b.

A man heterozygous for both traits ( DdBb) marries a women who has no dimple and heterozygous fro eyebrow (ddBb)

So cross is = DdBb × ddBb

1). Genotype of the man is DdBb.

2). Genotype of the woman is ddBb.

3). Genotype of the gametes produced by the man are DB, Db, dB and db.

4). Genotype of the gametes produced by the woman are dB and db.

5). Probability that their first child will have dimples 50% or 1/2

6). Probability that there first child will have both dimples as well as slender eyebrows 1/8

Despite the high-level of biodiversity, this biome has infertile soils, principally oxisols, to which the vegetation has roots s

irina [24]

The biome that has infertile soil, principally oxisols, to which the vegetation <span>has roots systems that capture nutrients from litter decay, is the tropical rainforest.

Soil types are highly variable in the tropics and are the result of a combination of several elements or variables which includes climate, vegetation, topographic position, parent material and also the soil age. Most of the tropical soils are described by leaching and poor nutrients. It also has two classifications: namely the ultisols and oxisols. Ultisols are known as well-weathered, acidic red clays soils. They are deficient primarily in major nutrients such as potassium and calcium. Oxisols are also an acidic type of tropical soil. However, they are well drained compared to the ultisols.

Explanation:

The invasive species are dangerous to natural resources because they destroy the natural resources and ecological system.

These invasive species are controlled by the biological control and mechanical control.

Thus to prevent the invasive species from entering texas freshwater ecosystem the following steps are taken they are

Always clean and dry any equipment used in or around lakes or rivers after each use.

Will give brainliest to first correct answer.<br><br> Explain how the superbug was created.

jolli1 [7]

Answer:

A superbug refers to a germ that has formed resistance to multiple drugs that once treated the infection caused by the germ. The term “superbug” was developed by the media. While any germ may become a superbug, bacterial and fungal strains that routinely infect humans, animals, and crops are most likely to do so.

Superbugs are strains of bacteria that are resistant to several types of antibiotics. ... And the overuse and misuse of antibiotics helps to create drug-resistant bacteria. Here's how that might happen. When used properly, antibiotics can help destroy disease-causing bacteria.
