Internal membrane connected to the external membrane where energy production may occur and which may help cell division

1 answer:

4 0

Mitochondria are unusual organelles. They act as the power plants of the cell, are surrounded by two membranes, and have their own genome. They also divide independently of the cell in which they reside, meaning mitochondrial replication is not coupled to cell division. Some of these features are holdovers from the ancient ancestors of mitochondria, which were likely free-living prokaryotes.

<u>Note</u>: I have provided my own definition for the ninth term (firn) in the third image for which the definition was missing

<u>Answer</u>:

A. 1. The height of anything above a given planetary reference place, especially above sea level on Earth, the extend of distance upward - <u><em>altitude </em></u>

2. The movement of glacial ice and snow as a result of gravity - <em><u>basal slip</u></em>

3. When chunks of ice break off at the terminus, or end of a glacier - <em><u>calving</u></em>

4. An amphitheater like valley formed by glacial erosion - <em><u>cirque</u></em>

5. A long period of cold climate where glaciers cover large parts of the earth - <em><u>ice age </u></em>

6. Miniature ice sheet - <u><em>ice cap</em></u>

7. The angular distance of a place north or south of the Earth’s equator usually expressed in degrees and minutes - <em><u>latitude</u></em>

8. The study of the Earth’s atmosphere in prehistoric times - <em><u>paleoclimatology</u></em>

9. Below the surface in the region under enough pressure that the ice is no longer brittle the ice distorts and changes shape due to the pressure of the above layers - <em><u>plastic flow</u></em>

10. When a glacier loses more snow and ice due to melting and calving than it accumulates - <em><u>glacial retreat</u></em>

B. 1. A deep crack or area of cracks that result from the upper layer of the glacier ice breaking when the lower layer of ice flows - <em><u>crevasses, aka zone of fracture </u></em>

2. Snow accumulation converted into granular ice over time - <em><u>zone of accumulation </u></em>

3. A boulder left behind by a glacier - <em><u>glacial erratic</u></em>

4. Scratches or gouges cut into bedrock by glacial abrasion or rubbing - <em><u>glacial grooves or striations</u></em>

5. Unsorted sediment deposited directly when glacial ice melts - <em><u>moraine </u></em>

6. A pile of rocks left behind by a glacier - <em><u>glacial till </u></em>

7. The location on a mountain glacier when the rate of accumulation is equivalent to the rate of melting - <em><u>snowline or equilibrium line </u></em>

8. the terminus or down-slope end of the glacier where ice and snow are melting faster than accumulating - <em><u>zone of ablation (or wastage) </u></em>

9. <em><u>Firn</u></em> = crystalline or granular snow that has not yet been compressed into ice. If is found especially on the upper part of a glacier

<h2>(Answer 1 points 3)</h2><h2>A. Taxon</h2><h3>3. the categories used in classifying organisms.</h3><h2>Explanation:</h2>

In other words, we can also say that taxon is also known as a taxonomic group of any rank, such as a species, family, or class. It is a group of one or more than one different populations of an organism or the organisms viewed by taxonomists to make a system. These are the rules for naming new animals.

<h2>(Answer 2 points 3)</h2><h2>B. Taxonomy</h2><h3>1. the science of the classification of organisms.</h3><h2>Explanation:</h2>

A taxonomy is said to be a scheme of classification or in other words, we can also define the term taxonomy as the branch of science involved with classification, especially of organisms, systematics. Organisms are grouped together. This science of gives name, describe and classify the organisms including all the plants, animals and the microorganisms of the world.

<h2>(Answer 3 points 3)</h2><h2>C. Family</h2><h3>4. A taxonomic category containing a group of similar genera.</h3><h2>Explanation:</h2>

Family is the one that has been classified between order and genus. A family is also divided into the subfamilies. It is one of the eight main and important taxonomic levels. It is a primary taxonomic category of organisms ranking. This category comes on the sixth number of all the categories lies in a taxonomic group.

<h2>(Answer 4 points 3)</h2><h2>D. domain</h2><h3>2. The largest taxonomic category.</h3><h2>Explanation:</h2>

In the three-domain system of taxonomy, if we talk about the domain then we would define it as the superkingdom or empire. It can also be said to be as it is the highest taxonomic rank of organisms. It is a taxonomic category above the kingdom level. There are three domain such as Bacteria, Archean, and Eukarya, which we can say are the major categories of life.

Viefleur [7K]

Answer:

c. Directional selection

Explanation:

There are three types of selection: stabilizing, directional and disruptive. Currently seed cracker finches show disruptive selection with respect to bills. In disruptive selection two extreme phenotypes are preferred in population over the mean phenotype. Here either, small or large bills are beneficial for birds so it is an example of disruptive selection.

If due to some climatic change all seeds would become hard, it would be more beneficial for birds to have large bills. Slowly nature will select for birds with large bills rather than birds with small bills. The selection now will shift to directional selection since only one of the extreme phenotypes is being favoured.

Planet X
Explanation:
The orbital radii of planet X is the smallest which means that is closest to the sun. The distance to the star determines the temperature of the planet. Closer the planet, more likely it would have higher temperature. So planet X has highest temperature most likely.
In the solar system, there is exception, mercury is closest to sun but Venus which is the second planet from the sun has highest temperature. This is because mercury has no atmosphere and Venus has very thick atmosphere which traps the solar radiation and heats up.
