1. Compare and Contrast prokaryote and eukaryote cells

1 answer:

5 0

1: Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.

2: Eukaryotes represent a domain of life, but within this domain there are multiple kingdoms. The most common classification creates four kingdoms in this domain: Protista, Fungi, Plantae, and Animalia. The four kingdoms of living organisms are unique in their own way. You can go to a wikipedia page for more about this.

3: animal, human, bacteria, amoeba, and mushroom. (May be wrong)

4: organelle, cells, tissues, organs, organ systems.

5: In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in a taxonomic hierarchy. Examples of taxonomic ranks are species, genus, family, order, class, phylum, kingdom, domain, etc.

3.6 In mice, the allele C for colored fur is dominant over the allele c for white fur, and the allele V for normal behavior is d

KengaRu [80]

Answer:

a) Parents Genotype should be (CC,Vv) and (cc,VV).

b) The genotypes of the parents are (Cc,Vv) and (Cc,Vv).

c) The genotypes of the parents are (Cc,Vv) and (cc,vv).

Explanation:

Mating has occured between a normal colored mice whose genotype is C_,V_ and normal white mice with genotype cc,V_. The offsprings are as follows :

1) normal mice produced 29 colored

2) 10 colored, waltzing progeny.

Thus all offspring are normal. The genotype of the first parent should therefore be CC. Waltzing trait is produced. The V gene should therefore be heterozygous in both traits.

Hence The parent genotypes should be<u> (CC,Vv) and (cc,CV).</u>

In this case the approximate ratio in which the descendants are produced is 9:3:3:1. Hence genotypes of the parents are <u>(Cc,Vv) and (Cc,Vv). </u>

In this case the approximate ratio in which the offsprings are produced is 1:1:1. The genotypes of the parents are <u>(Cc,Vv) and (cc,vv). </u>

<span>Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. (Domesticated) animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as (varieties), cultigens, or cultivars. Two purebred animals of different breeds produce a (crossbreed). Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. </span>

Denticulate ligaments are thickenings of _________ that extend and fuse with the ______ and inner surface of the _____a.arachnoi

Lemur [1.5K]

Answer:

* ARACHNOID MATER

*DURA MATER

*PIA MATER

Explanation:

denticulate ligaments are bilateral extensions of pia mater that thickening the component of collagen of pia mater.It anchors the spinal cord to the dura mater.They are produced by the pia mater of the spinal cord.They provide stability to the spinal cord within the vertebral canal.

Arachnoid mater helps protect the brain and spinal cord from sudden impact. It is connected to the dura mater at the side that is very close to the central nervous system.

Dura mater refers to the membrane that envelops the arachnoid mater. It surrounds the dural sinuses and also provide supports to it. Dura mater carries blood from the brain toward the heart.

The pia mater is part of pseudolymphatic system and it's referred to as the thin fibrous tissue that allows blood vessels to pass through the brain.

Which statement describes the relationship between a gene and an allele?

omeli [17]

Answer: option B) A gene can take different forms called alleles.

Explanation:

An allele is one of the two or more different forms of the same gene.

For example, a trait such as seed shape is represented expressed a gene, but with allele of "RR" (round seeds) and "rr"(wrinkled seeds) observed physically by the farmers.

Thus, the correct answer is that a gene can take different forms called alleles.
