Nearly all eukaryotic cells contain a class of small, round organelles that contain oxidative enzymes. The enzymes break down or

Ivenika [448]

The correct answer is peroxisomes.

Peroxisome refers to a small organelle found in the cytoplasm of various cells that comprises catalase (the reducing enzyme) and generally some oxidases.

They are the minute vesicles and comprises the digestive enzymes used for dissociating toxic components in the cell. They are not similar to lysosomes on the basis of the kind of enzymes they withheld. The peroxisomes generally contain enzymes that need oxygen, that is, oxidative enzymes.

PLEASE HELP!! 36 POINTS!!!

Serhud [2]

Answer:

Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.

Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).

Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).

Natural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or disruptive selection.

Introduction

We've already met a few different mechanisms of evolution. Genetic drift, migration, mutation...the list goes on. All of these mechanisms can make a population evolve, or change in its genetic makeup over generations.

But there's one mechanism of evolution that's a bit more famous than the others, and that's natural selection. What makes natural selection so special? Out of all the mechanisms of evolution, it's the only one that can consistently make populations adapted, or better-suited for their environment, over time.

You may have already seen natural selection as part of Darwin’s theory of evolution. In this article, we will dive deeper – in fact, deeper than Darwin himself could go. We will examine natural selection at the level of population genetics, in terms of allele, genotype, and phenotype frequencies.

Quick review of natural selection

Here is a quick reminder of how a population evolves by natural selection:

Organisms with heritable (genetically determined) features that help them survive and reproduce in a particular environment tend to leave more offspring than their peers.

If this continues over generations, the heritable features that aid survival and reproduction will become more and more common in the population.

The population will not only evolve (change in its genetic makeup and inherited traits), but will evolve in such a way that it becomes adapted, or better-suited, to its environment.

Standard radiographic protocols may be reduced to include two views, at right angles to each other, in which of the following si

Vesnalui [34]

A: no

In barium examinations, you want to see if something it's obstructing, like the colon. You only use a front view.

B: yes

When you want to see if everything it's alright about the spine, you need to analyze the curvature, and for that, you need front and side view.

And, is the only radiographic tool that can be done in antero-posterior and lateral views.

C: no

When you are looking for trauma or bone breakage, you may need only a side view or front view.

D: yes

If you are looking for any trauma or emergency, you need different positions of the bone to discover any breakage.

Which of the following statements is true? A. Water heats up and cools down more quickly than land B. In the Southern Hemisphere

mina [271]

Answer:

The answer is C

Explanation:

Because the earth's surface is made up of different types of land and water, it absorbs the sun's heat at different rates. One example of this uneven heating is the daily wind cycle.
