What are 2 suffixes that the scientific sugar names end with?

1 answer:

8 0

The two suffixes that scientific sugar names end with would be -ose and -saccharide. Most often, when chemicals are sugars their names end in -ose, such as glucose and fructose. However, -saccharide is a Greek term which means sugar. Given that their scientific nomenclature are complex, monosaccharides and disaccharides often end in the suffix -ose.

In gorillas, the ability to roll the tongue is under the control of 1 gene. The R allele, which confers tongue-rolling ability,

aalyn [17]

Answer:

0.4550

Explanation:

In this example, R allele is dominant, so individuals RR and Rr can roll their tongues. If in a population of 1000 gorillas, there are 575 gorillas who can roll their tongues, they will be RR and Rr.

In this case, there is Hardy Weinberg Equilibrium, so the following will be true:

$p^{2}+2pq+q^{2}=1$

Where:

$p^{2}=$ frequency of RR

$2pq=$ frequency of Rr

$q^{2}=$ frequency of rr

The question is what is the frequency of heterozygotes, or, what is the value of 2pq.

We know that RR+Rr is 575 individuals in a population of 1000, or 0.575.

In other words:

$p^{2}+2pq=0.575$

So, it is possible to find $q^{2}$ :

$q^{2}= 1-2pq-p^{2} \\q^{2}=1-(0.575)\\q^{2}=0.425$

Now, there are two alleles in the population, so the following will be true:

$p+q=1$

It is possible to find q (the frequency of allele r) and p (the frequency of allele p):

$q=\sqrt{q^{2} }\\ q=\sqrt{0.425} \\q=0.652$

Therefore:

$p=1-q\\p=1-0.652\\p=0.348$

Now, the frequency of heterozygotes or 2pq is:

$2pq=2*0.652*0.348\\2pq=0.45$

How might a population crash be related to resource availability in the environment or the carrying capacity of the ecosystem?

d1i1m1o1n [39]

Answer:

To a certain extent, population numbers are self-regulating because deaths increase when a population exceeds its carrying capacity. Disease, competition, predator-prey interaction, resource use and the number of populations in an ecosystem all affect carrying capacity.

You examine an epithelial cell (skin cell) and notice the chromosomes are visible however it appears there are two nuclei in the

krek1111 [17]

Answer:

The best explanation if we observe an epithelial cell with chromosomes are visible and two cell nuclei is that the cell has just gone through telophase but not cytokinesis (option b).

Explanation:

A somatic cell, when found in mitosis, exhibits the chromosomes distributed in both poles and the outline of two nuclei in the telophase phase, just before cytokinesis.

In mitotic telophase:

Chromatids, which are chromosomes, are found in the cell poles.
It initiates the formation of the nucleus membrane.
The chromosomes begin to turn into chromatin.
Disappearance of the mitotic spindle, duplication of organelles and cytoplasmic invagination.

The division and differentiation of the nuclei in telophase is called karyokinesis. Later, cytokinesis occurs, where the daughter cells are separated.

The other options are not correct because:

a and d. In the other phases described, S and G1, no chromosome distribution is observed at the poles.

c. A somatic cell does not experience meiosis.
