Using the allele symbols in the table, identify the genotype of a guinea pig that is recessive for hair length, heterozygous for hair color, and homzygous dominant for hair texture.
Answers
Answer:
Hair length: hh
Hair color: Bb
Hair Texture: RR
Explanation:
In order for the recessive gene to show for hair length, two of the same alleles must be present, so, in this case, hh.
The question states "heterozygous for hair color." This tells you that the genotype will be Bb. Heterozygous means two of the different alleles. This is different from homzygous.
The question states "homzygous dominant for hair texture." This tells you that it will contain two of the same alleles. The question also tells you that it is homzygous dominant, which means there will be two of the same dominant alleles, so, RR.

energy
Answers
Answer:
Energy
Explanation:
Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.

all plant bodies(root,stem and leaf) are externally covered by epidermis but why woody plant is covered by barks
Answers
Answer:
Bark comprises all the tissues surrounding the xylem in woody plants. Broadly, bark includes an inner and mostly living region and an outer, dead one. Of all plant structures, bark has the most complex anatomical structure and ontogenetic origin involving two (and often three) different meristems.
As to why, the bark adds layers to the inside ring of the vascular cambium, the outside is pushed outward. The cells die off, and the fibrous matrix of cellulose and lignin molecules remain. This hard structure forms the bark, and protects the tree or plant from many forms of damage.

Answers
Answer:
They bloom when the nights are longer.
Answer:

Photoperiodism means the reaction to length of a day or night cycle, since fall is the beginning of shorter days and longer nights, it is only reasonable that the answer is that They bloom when the nights are longer.
All of the following are used by taxonomists to create evolutionary links between species EXCEPT
Select one:
a. analogous structures
b. the fossil record
c. molecular data
d. vestigial structures
Answers
The fossil record, molecular data and vestigial structure would help taxonomists to create evolutionary links between species except analogous structures.
What do you mean by fossil record?"A fossil record is a group of fossils which has been analyzed and arranged chronologically and in taxonomic order."What is molecular data?"Molecules such as sequence of DNA used in studies of intra-specific variation and studies of similarity among species."What is vestigial structure?"Structures that have no apparent function and appear to be residual parts from a past ancestor are called vestigial structures."What do you mean by taxonomists?"Taxonomists are professionals who specialize in classifying and sorting information based on similar characteristics and patterns."What are analogous structures?The structure of different species performing similar function but are from different origin (do not have common ancestor).The fossil record, molecular data and vestigial structure all would help taxonomists to find evolutionary links between species where through analogous structures no links would be created.
Hence, the correct option is a. analogous structures.

Help me past due Write down what you think will happen to the density of water if you add salt or sugar.
Answers
Answer:
If I add sugar or salt, the water's density will increase.
Explanation:
Density is the relation between mass and volume. We can represent it with the formula δ= m/v. Where δ stans for density, m for mass, v for volume.
If we add salt or sugar, we increase the mass, but the volume is the same. As a result, the density will increase.
We can use numbers to understand it better.
Suppose that before adding salt or sugar, the mass is 1 g and the volume is 1 l
δ= 1g/l1t
δ= 1 g/lt
Now, if we add sugar or salt, the mass increases. Suppose that we have 2g of mass and the volume is the same, 1l.
δ= 2g/1lt
δ= 2g/lt
We can see that the density increased when the mass increased.
