What happens during cytokinesis?

Which of the following is an organism whose cells each contain a membrane bound nucleus?

DerKrebs [107]

Answer:

D. Eukaryote

Explanation:

An organism that has membrane-bound organelles will have more complex organelles like mitochondria, Golgi apparatus, and ER. These are known as Eukaryotes. Additionally, they will have a nucleus that has the DNA coiled inside. Prokaryotes do not have membrane-bound organelle and the DNA floats in the cytoplasm. Most plants and animals are eukaryotes and all multicellular organisms are too.

Discuss the importance of a balanced diet.

Aliun [14]

Answer:

u need a healthy diet cause it gives u the nutrients and energy u need to survive. ur body is more prone to disease n infections if u dont have a balanced diet. immune system weakens if u eat nutrient-poor foods. also here's something i copy-pasted from a random website:

revents diseases and infections. When you eat the full range of vitamins, minerals and other nutrients you improve your immune system and your healthy diet may even help prevent diseases like cancer, heart disease, diabetes, and stroke.

Helps you control your weight. Most people at some point want to lose weight or gain weight – eating a balanced diet helps you control your weight and maintain it over time. It is not feasible to be on a weight-loss diet forever – a balanced diet is the only way to healthily control your weight in the long term.

Improves your mental health. Getting the right mix of nutrients can help to ease symptoms of depression and anxiety – looking after yourself by eating well is essential as you take steps to good mental health.

Good for growth. A balanced diet is crucial for children and adolescents. As the body grows it is important to receive the right nutrients so that cells are built and maintained and the body grows at the right pace.

Better skin and hair. A healthy balanced diet also improves your looks. Eating well contributes to healthy skin and hair and a “glow” that makes you look younger.

this isnt very science-y but i tried to help the best i could so this should give u starting off point. have a great day/night

Suppose two independently assorting genes are involved in the pathway that determines fruit color in squash. These genes interac

makvit [3.9K]

Answer:

100% yellow fruit color, Yyww.

Explanation:

Available data:

two independently assorting genes

the W allele codes for a dominant white phenotype

w allele codes for a colored squash

The allele Y codes for a dominant yellow phenotype

the allele y codes for a recessive green phenotype

The phenotypes from the first locus will always mask the phenotype produced by the second locus if the dominant allele (W) is present at the first locus. This masking pattern is known as dominant epistasis

Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". When the epistatic gene is dominant, the interaction is known as "dominant epistasis".

W suppresses the expression of Y and y, this means that whenever W is present, the fruit is white. If W is not present, the fruit color can be expressed.

So, the proposed cross in the present problem occurs between a green fruited individual and yellow fruited individual, which suggests that W is absent.

Genotype for Green fruit: yyww

Genotype for purebred Yellow fruit: YYww

Cross:

Parental) YYww x yyww

Gametes) Yw Yw Yw Yw yw yw yw yw

Punnet square) Yw Yw Yw Yw

yw Yyww Yyww Yyww Yyww

F1) 100% Yellow fruited plants, Yyww

As these two genes assort independently, we can also represent the cross for each gene by separate, like this:

For w gene:

Parental) ww x ww

Gametes) w w w w

Punnet square) w w

w ww ww

F1) 4/4 or 100% colored-fruits

For Y gene:

Parental) YY x yy

Gametes) Y Y y y

Punnet square) Y Y

y Yy Yy

F1) 4/4 or 100% yellow fruits, Yy.

What type of RNA is a major component of the structure at which protein synthesis occurs? nuclear RNA messenger RNA ri

Ray Of Light [21]

Answer:

B) Messenger RNA

Explanation:

Messenger RNA [mRNA] molecules carry the coding sequences for protein synthesis and are called transcripts.Ribosomal RNA [rRNA] molecules form the core of a cell's ribosomes [the structures in which protein synthesis takes place] and transfer RNA [mRNA] molecules carry amino acids to the ribosomes during protein

An offspring's inherited traits come not from one parent only but from both. True False

Novay_Z [31]

True. If you make a punnet square you get the traits which come from both parents.
