MissTica3 years ago

One of the cell technologies that was made possible by micromanipulation tools is reproductive cloning.

Reproductive cloning is a form of artificial reproduction using the cloning technique. It is distinguished from therapeutic cloning or, more properly, cloning for therapeutic purposes.

There are two cloning methods that could be considered for human reproduction: cloning by cleavage of a blastocyst, and cloning by transfer of a cell nucleus into an enucleated ovum.

nydimaria [60]

Answer:

C. Atoms can be used over and over in different molecules

Explanation:

When different compounds enter the stomach, they undergo a series of chemical reactions and are broken down. They are then used for new metabolic processes. For example, if glucose was broken down into pure Carbons, they could then react and form other molecules as needed by the body.

The plasma membrane of the sea urchin egg ______. A. is outside of the fertilization membrane B. releases calcium, which initiat
Butoxors [25]

The plasma membrane of the sea urchin egg has receptor molecules that are specific for binding acrosomal proteins .

<h3>What is plasma membrane ?</h3>

Plasma membrane is the outermost covering of the body which selectively permits the entry and exit of different type of materials .

Thus ,it is also called as selectively permeable membrane.it also separates the inner and outer environment of the cell .

It also helps in the diffusion process .

PolarNik [594]
1a. Pseudopodia means false feet these are irregular projections found in organisms like amoeba,they help the organism in locomotion capture food etc
1b.a good vacuole is a membrane-enclosed cell vacuole with a digestive system,containing material taken up in by the process of phagocytosis.these are found in amoeba,Protozoa,paramecium
2.the ingestion of bacteria or other material by phagocytes and amoeboid protozoans (wasn’t sure for this one so I had to research)
3.amoeba takes in nutrition by the process called phagocytosis.in this process,a solid food particle is first surrounded by pseudopodia (cytoplasmic filled projection of cell membrane) and forms a vacuole called as Phagosome

Please mark me as brainliest or please say this is helpful

I hope this helps if you have any more questions just message me

The LMand LNalleles at the MN blood-group locus exhibit codominance. Give the expected genotypes and phenotypes and their ratios
Dmitry [639]

Answer:

Please find the expected genotypes and phenotypes of the progenies of each cross below.

Explanation:

In the MN blood-group locus of the gene, alleles LM and LN exhibit codominance i.e one allele is not dominant or recessive to the other, hence, they are both expressed when they occur in a heterozygous state (MN).

Considering the following crosses (find the punnet square attached);

a)LMLM x LMLN - The progeny are LMLM and LMLN in the genotypic ratio 1:1. Phenotypic ratio is Blood type M (1) : blood type MN (1)

b) LNLN x LNLN - The progeny are all LNLN offsprings with a phenotypic and genotypic ratio 4:0. All offsprings will have a blood type N (4)

c) LMLN x LMLN - The progenies are LMLM, LMLN and LNLN in the genotypic ratio 1:2:1 respectively. The phenotypic ratio is Blood type M (1) : L

Blood type MN (2) : Blood type N (1)

d) LMLN x LNLN - The progeny are LMLN and LNLN with genotypic ratio 1:1 and phenotypic ratio blood type MN (1) : blood type N (1)

e) LMLM x LNLN - The progeny are all LMLN offsprings with penotypic ratio blood type MN (4)
