What ratio of plants in the offspring would you predict from a Yy x Yy cross?

Biology
1 answer:
ziro4ka [17]3 years ago
3 0

Answer:

The correct answer is -

The genotype of offspring - 1:2:1 (YY:Yy:yy)

The phenotype of offspring - 3:1 (dominant trait: recessive trait)

Explanation:

In this question, it is stated that there is a cross between Yy and Yy. By the genotype of the parents, we can say that Y is dominant for a particular trait and y is recessive and the parents are in the heterozygous condition in this cross. The gametes these parents will produce are - Y and y and Y and y

then the cross of Yy and Yy would be -

      Y      y

Y    YY    Yy

y     Yy    yy

Offspring from this cross are YY, Yy, Yy, and yy which means the genotypic ratio is - 1:2:1 and the phenotypic ratio is - 3:1 as three out of four are dominant.

Which one of the following processes does not occur to excess neurotransmitters in the synapse
svlad2 [7]

This question is incomplete because the options are not given; here is the complete question:

Which one of the following processes does not occur to excess neurotransmitters in the synapse?

A. Break down or digested into inactive fragments.

B. Collection by scavenger vesicles left over from the neurotransmitter release.

C. Drifting away from the synapse via diffusion.

D. Reuptake within the pre-synaptic neuron.

The answer to this question is B. Collection by scavenger vesicles left over from the neurotransmitter release.

Explanation:

The word synapse refers to the neurological structure that allows the transmission of signals or information between neurons. This process occurs through neurotransmitters, which are the molecules or substances with the messages.

Moreover, in this process, there can be in some cases excess. In this situation, the body reacts to this excess by degrading or breaking down the extra neurotransmitters, eliminating it through diffusion, or even reabsorbing it (reuptake). In this context, all are processes that occur due to excess neurotransmitters except collection by scavenger vesicles because in most cases neurotransmitters are simply absorbed or eliminated but there are not specialized scavenger vesicles that collect them.

If macro molecules are known as polymers why is each subunit known as a monomer?
s344n2d4d5 [400]
In the text it says “Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. ... In the process, a water molecule is formed.” I hope this helped

A strand of DNA that is 36 nucleotides long codes for how many amino acids?
Margarita [4]

Answer:

See answer below

Explanation:

Hi there,

Assuming this DNA strand is fully capable of being mature mRNA (5' m7G cap and PolyA tail), nucleotides lead to an mRNA codon, which is 3 nucleotides per codon. In turn, 1 codon leads to 1 amino acid. However, as a single strand, it must be capable of terminating translation, which always requires a stop codon, and thus 3 nucleotides. Hence, we must subtract this from the total amount of codons <em>first</em>.

36 \ ncltd \ \frac{1 \ codon}{3 \ ncltd} = 12 \ codon\\12 \ codon - 1 \ codon \  = 11 \ codon\\11 \ codons\ \frac{1 A.A.}{1 \ codon}  = 11 \ A. A.

Hence, only 11 amino acids will be coded by a single DNA strand 36 ncltd long.

thanks,
