In one type of dog, black spots (B) are dominant over brown spots (b) and long tails (L) are dominant over short tails (l). Complete a dihybrid cross for parents with the genotypes: BbLL × BBLl and answer the following in complete sentences. Describe how you would set up a Punnett square for this cross.
List the likelihood of each possible offspring genotype.
List the likelihood of each possible offspring phenotype.
Genotypes of offspring will be BBLL, BbLL, BBLl, and BbLl.
The phenotype of offspring will be all black spots with long tails.
A cross between BbLL and BBLl will form BL, bL, and Bl, BL gametes respectively. All gametes will assort independently and produce offspring of with different genotypes,
The genotype of possible offsprings will be - 25% BBLL (black spot dog with long tail), 25% BbLL (Black spot dog with long tail), 25% BBLl (black spot dog with long tail) and 25% BbLl (black spot dog with long tail)
The phenotype of possible offsprings will be - 100% black spot dog with long tail because there always a copy of dominant alleles are present in the genotype of each offspring.
How does immune system work together with the circulatory system
Are similar to basophils, but reside in tissues rather than circulating in the blood.
The correct answer is mast cells.
Mastocyte also is known as a mast cell refers to a migrant cell of connective tissue, which comprises various granules high in heparin and histamine. Mainly it is a kind of granulocyte obtained from the myeloid stem cell, which is a component of the neuroimmune and immune systems. These cells are similar to basophils, however, they are found within the tissues rather than circulating in the blood.

B. mountain communities.
C. coastal farmland.
D. coastal cities.
The correct answer is C
The correct answer is C. Coastal Farmland
The one change that is made by the scientist is called the
The one change that is made by a scientist is the independent variable while the dependent stays the same. They change the independent variable to see the results of what would happen if they moved their experiment somewhere else or etc.

One of the three main functions of stems is to A. carry out photosynthesis.
B. carry water and nutrients between roots and leaves.
C. store carbohydrates.
D. store water.
One of the three main functions of stems is to carry water and nutrients between roots and leaves. So, the correct option is B.What is Stem?
The stem is defined as the axis of the plant that bears buds and shoots with leaves and, at its basal end, roots that conduct water, minerals, and food to other parts of the plant, which store food and the green stem itself produces food.
Stem is explained as the aerial part of the plant which contains leaves, fruits, branches and flowers. The stem is positively phototropic and negatively geotropic where as the leaves contain chlorophyll so that the plant can make food. The main functions of stems is to carry water and nutrients between roots and leaves.
Therefore, the correct option is B.

Where are the grana located?
Identify the characteristic or function all roots have in common. A. roots take in water B. roots have two layers C. roots grow underground D. roots store food
the answwer is A. because The root hairs are where most water absorption happens. ... The function of root hairs is to collect water and mineral nutrients present in the soil and take this solution up through the roots to the rest of the plant.
A - Roots take in water
Richard is an avid gardener who spends a lot of time caring for the plants in his garden. To minimize damage from pests from his garden, Richard uses a pesticide spray. At first the spray is very effective and kills off most of the insects that he sees on his vegetable plants. However, after a few years of using the same pesticide he notices that some insects are surviving and continuing to eat his plants. This selection for herbicide resistance in the insects is an example ofa. natural selection.b. evolution.c. an adaptation.d. a gene.e. a learned response.
a. Natural selection
The pesticide killed off all of the pest that weren't immune to it and the pests that were immune reproduced with each other creating offspring that were immune to it as well and so on this is a example of natural selection.
