Answer:

They are eukaryotic cells because two or more cells make up tissue and prokayotic cells are unicellular (means they are one-celled).

The answer is eukaryotic. Eukaryotes are characterized by having a nucleus in their cells. They keep cells together in a sheet-like formation in organs and tissues that stretch, like the skin and muscles including the heart.

In the presence of a non-competitive inhibitor a Lineweaver-Burk plot has a higher y-intercept than a control (without any inhib

konstantin123 [22]

Answer:

The Lineweaver- Burk plot is representation of Lineweaver-Burk equation of enzyme kinetics in graphical plot that is presented by the Hans Lineweaver and Dean Burk.

In the presence of a non competitive inhibitor shows higher y-intercept than a control in absence of any inhibitor whereas the x intercept is the same as the control that suggests or tells that maximum enzyme activity of the reaction is decreased, Higher Y intercept than controls means that it is same as 1/Vmax. The X intercept indicates that there is no effect on Km of the enzyme reaction.

Round seeds and yellow seed color are dominant to wrinkled seeds and green seed color. What is the probability of having offspri

adoni [48]

Answer:

<h2>The probability of a cross between RRYY x RrYy to generate a yellow and wrinkled seed offspring is 0%.</h2>

Explanation:

Circular and yellow seeds are overwhelming and wrinkled and green seeds are passive. It is vital to keep in mind that resective characteristics are as it were displayed when the sibling has two passive alleles for those characteristic, in the event that the descendant includes a latent allele and a overwhelming allele, the characteristic that will be presented is the overwhelming one. For this reason, able to say that a cross between RRYY x RrYy plants, would not create any descendant with wrinkled and yellow seeds. Typically since, the descendant of a crossing, must show an allele of each parent. One parent as it were has overwhelming alleles (RRYY), so able to say that all descendant will get 1 overwhelming allele for color and a overwhelming allele for seed surface, anticipating the sibling from communicating latent characteristics.

Ecosystem services include processes that increase the quality of the abiotic environment. Which of the following processes woul

slega [8]

Answer:

Option D, only II, III, and IV

Explanation:

Complete Question

Ecosystem services include processes that increase the quality of the abiotic environment. Which of the following processes would fall under this category?

I) Keystone predators have a marked effect on species diversity.

II) Green plants produce the oxygen we breathe.

III) The presence of land plants builds soil.

IV) The presence of diverse wetlands helps in flood control.

A) only II and IV

B) only I and III

C) only I, II, and IV

D) only II, III, and IV

Solution -

The services of ecosystem has been classified into four groups

a) Provisioning – Where essential abiotic and biotic substance are produces such as production of food and water, reproducing offspring etc.

b) Regulating – the ecosystems is controlled through environmental factors such as control of climate and disease

c) Supporting – Ecosystem support the activities that are essential for survival. Primarily includes all nutrient cycles, oxygen generation etc.

d) Cultural – Provide aesthetic view and recreational benefits

Option II co mes under supporting service of ecosystem

Option III co mes under Provisioning service of ecosystem

Option IV co mes under Regulating service of ecosystem

Hence, option D is correct

For larger distances such as the distance between objects in the far reaches of our galaxy astronomers ensure in units of?

Scorpion4ik [409]

Answer:

Lightyears

Explanation:

When dealing with very large interstellar distances, astronomers do not use the regular miles, kilometers, or meters we are used to. This is because they are just too small to be used as a metric when measuring such large distances. As a matter of fact, the earthly number system will quickly be exhausted when trying to measure some of these interstellar distances.

Instead, astronomers make use of Lightyears. Lightyears are defined by the distance traveled by an object moving at the speed of light if it was moving constantly at that speed for one year.

This can properly be used to estimate interstellar distances. since its value is very large. 1 lightyear = 9,461,000,000,000 Km

If we say that our closest star is 9 lightyears away, we are saying that it will take an object moving at the speed of light 9 years to travel from that star to our planet.
