Answer: D

Explanation:

Okay so look at the diagram. Start from the middle and work your way out.

AUG: I find A in the middle (the first four) and then go to the part of the diagram that has U right under the last letter you had, so A. And do the same for U, and you should get methionine.

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.

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

A Analogous structures

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.

Explain why a topographic map has a key.

Answers


Topographic maps represent the locations of geographical features, such as hills and valleys. Topographic maps use contour lines to show different elevations on a map. A contour line is a type of isoline; in this case, a line of equal elevation. If you walk along a contour line you will not go uphill or downhill.

Topographic maps represent the locations of geographical features, such as hills and valleys.

What do you mean by topographic maps?

Topographic maps use contour lines to show different elevations on a map. A contour line is a type of isoline; in this case, a line of equal elevation.

In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief features, usually using contour lines.

A topographic map is a detailed and accurate illustration of man-made and natural features on the ground such as roads, railways, power transmission lines, contours, elevations, rivers, lakes.

Why is it important that the seedling’s true leaves grow quickly?HURRY IM BEING TIMED

to help disperse seeds to areas where they can grow
to shield the seedling from too much water or rain
to protect the seedling from receiving too much sunlight
to make food for the seedling’s continued growth

Answers

Answer:

The correct answer is - to make food for the seedling’s continued growth.

Explanation:

The true leaves that emerge from the seedlings are the leaves that are capable of performing photosynthesis and start generating food and energy. These support the plant for the rest of its life in terms of food and energy.

Seedlings grow from the soil, two leaves in beginning called cotyledons that are not the true leaves and not able to perform photosynthesis and generate their food for the seedling’s continued growth.

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.
