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:

<h2>1. DdBb</h2><h2>2. ddBb</h2><h2>3. DB, Db, dB and db.</h2><h2>4.  dB and db.</h2><h2>5 50% or 1/2</h2><h2>6. 1/8 </h2>

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

In your own words Describe how autotrophs and heterotrophs obtain energy. please this answer must be at least 150 words any one
blsea [12.9K]

The autotrophs are the primary producer in the food chain and they are the ones who initiate the food chain. They produce food by using sunlight or sometimes chemical energy or reactions. They primarily use carbon dioxide, sunlight and water to form sugars or carbohydrates which become their energy source. They use the process of photosynthesis or chemosynthesis to generate food. Examples of autotrophs are green plants, green algae, bacteria.

Heterotrophs cannot make their food via sunlight or other inorganic sources and hence are dependent on the autotrophs or other animals. The heterotrophs have been ranked as secondary and tertiary consumers and cannot be producers.  They consume the organic products made by autotrophs to obtain energy for various metabolic and biological activities. The heterotrophs can be herbivore, carnivore, fungi, parasitic plants.

Some are photo-hetrotrophs,  who use light as energy but cannot use carbon  dioxide as the carbon source since they cannot fix the carbon like autotrophs.

An organism's niche includes all of these except: a. the space an organism requires. b. the timing of an organism's reproduction
Viefleur [7K]

Answer:

c. the specific geographical location where an organism lives.

Explanation:

The ecological niche of an organism includes the habitat where it lives and its place in the community with respect to the other species. It includes various adaptations present in the organism to survive in prevailing conditions, its interaction with other biotic factors of the system, and the pattern of consumption of available resources. Therefore, the ecological niche of an organism defines the space occupied and its functional role in the community irrespective of the type of biome. It does not take account of its geographical location on the earth.
