Answer:
The direct threats of invasive species include preying on native species, outcompeting native species for food or other resources, causing or carrying disease, and preventing native species from reproducing or killing a native species' young.
Explanation:
When a BB male and a Bb female are crossed, 50% BB and 50% Bb genotypes are produced and a 100% black phenotype.
The entire number of genes that an organism receives from its parents makes up its genotype. Alleles, which are pairs of these genes, are found. One gene is dominant and one gene is recessive in each allele.
The dominant gene is always expressed in a cross if it is present. Only when a pair of alleles is made up of two recessive genes does the recessive gene express itself. In this instance, the white fur is subordinate to the black fur. White fur is represented as b, while black fur is represented as B.
We can see that when we cross the BB male and Bb female, we will get a genotype that is 50% BB and 50% Bb, as well as a phenotype that is 100% black fur.
Parents: BB x Bb
Gametes: B, B, and B, b
Offspring: BB, BB, Bb, Bb
The genotypic ratio = 1:1
The phenotypic ratio = 1:0
Genotype probabilities:
P(BB) = 2/4 = 0.5 or 50%
P(Bb) = 2/4 = 0.5 or 50%

Answer:
The correct answer is - option A. 1 (ovary).
Explanation:
Oocytes or egg are produced in the ovaries during the process of the female gametogenesis in female reproductive system. Ovaries are located on each side of the uterus that are oval and small in shape and size and located lower abdomen.
Among other female reproductive organs these are located above others. The ovaries produce oocytes and hormones It is the site at which primordial germ cell (PGC), become primary oocytes.
Thus, the correct answer is - option A. 1 (ovary).
<span> C.It transmits genetic information to the next generation. The key role of DNA is </span>to store genetic information for long term. It contains all components and basic structures of the cells, including RNA and proteins. They regulate how these genetic information will be expressed or transmitted.
1.) A feature that is not the direct result of glaciation is meander. The correct answer is A.
2.) Sedimentation is least likely to occur on a mountainside. The correct answer is A.
