Which of the following is a testable hypotheses

Explanation:

an amino group

Answer:

In typical amphibian development, eggs are laid in water and larvae are adapted to an aquatic lifestyle. Frogs, toads, and newts all hatch from the eggs as larvae with external gills but it will take some time for the amphibians to interact outside with pulmonary respiration. Afterwards, newt larvae start a predatory lifestyle, while tadpoles mostly scrape food off surfaces with their  tooth ridges.

Answer:

No. Because then every 2 years or so we would have to replace everything because the resource is limited

Explanation:

I would say yes. As non renewable energy  will come for a long time but once used up u cant get it again because they are over. but renewable energy even if it takes time to renew it will never get over. so in that way will be able to save non renewable energy for a more important purpose.

B. Red pandas and raccoons share a more recent common ancestor

than red pandas and giant pandas.

Explanation:

DNA sequencing is finding the sequence of base pairs in an organism's DNA, and it's often used to compare with other organisms. The more base pairs that are the same, the more similar the two organisms are, and this means that they share a more recent common ancestor.

We can't make any conclusions like C and D because we just don't have enough data to conclude that one descended from the other.

Answer: B

Explanation:

Red pandas and raccoons share a more recent common ancestor.

Hello

I think Reticulum is right.

Explanation:

Answer:

Yes

Explanation:

If u want to equate that with “luck” feel free. There are any number of points in natural history where any species, not just us, could have turned out very differently.

Had the climate not changed in Africa…. Forcing our distant relatives from the forested areas into the plains… We might very well still number among the “great apes” rather than the genus “Homo”.

There would be dozens of simialar “what ifs” in our past. The entire spectrum of life on Earth might have turned out very differently indeed had the Permian Extinction not happened…. Those life-forms that populated the Earth prior to this event were very different than those that evolved from the few survivors. (Over 90% of all life on Earth was presumed to have been killed off.)

The given question is incomplete, the complete question is:

Which of the following best describes the changes that take place in an ecosystem during primary succession?

Lichens and mosses grow slowly on newly formed land, followed by grasses, shrubs, and trees.

Shrubs and trees regrow quickly in areas that have been disturbed by a forest fire.

Organisms compete for resources, and those that are best fit to survive establish themselves as the dominant species.

Natural disasters cause many populations to migrate to a new location in order to survive

Answer:

The correct answer is that the growth of lichens and mosses takes place gradually on the freshly formed land, and is succeeded by shrubs, grasses, and trees.

Explanation:

An array of changes that takes place within an ecosystem's biotic community with regard to modifications that occurs with time within the non-living constituents of an ecosystem until stability is attained within the ecosystem is termed as ecological succession. A succession, which takes place in a previous barren land where there is no existence of life is known as primary succession.  

For example, a gradual growth of mosses and lichens on a freshly formed land, succeeded by shrubs, grasses, and trees is an illustration of primary succession. The pioneer species like mosses and lichens possesses the tendency to grow on the land, that is, not inhabited previously by any other species of plant and further helps in the growth of novel species of plants.  

On the bare rocks, lichens discharge acids that assist in the process of rock withering as it reduces the compaction of the rocks. Further, the aggregation of soil takes place that facilitates the growth of mosses. Eventually, the mosses help in bettering the quality of the soil, which further helps in the growth of shrubs, grasses, and trees.  

Answer:      Explanation:

The person who asked this question didn't put any choices, so I am going to give you some examples of primary and secondary successions.

Primary succession: it is the profession of growth, it developed on newly formed land.

Secondary succession: it is the redevelopment of a habitat that has been disturbed by an event such as a forest fire or a hurricane. “Tsunami, earthquake, or forest fire”

(A) Lichens and mosses grow slowly on newly formed land, followed by grasses, shrubs, and trees. 

(B) Shrubs and trees regrow quickly in areas that have been disturbed by a forest fire. 

(C) Organisms compete for resources, and those that are best fit to survive establish themselves as the dominant species. 

(D) Natural disasters cause many populations to migrate to a new location in order to survive.

(A) Lichens and mosses grow slowly on newly formed land, followed by grasses, shrubs, and trees. 

Because; "(B) Shrubs and trees regrow quickly in areas that have been disturbed by a forest fire" That is secondary succession, (redevelopment of a habitat that has been disturbed)

Because; "(C) Organisms compete for resources, and those that are best fit to survive establish themselves as the dominant species." Just doesn't fit the description for either Primary or secondary succession.

Because; "(D) Natural disasters cause many populations to migrate to a new location in order to survive." That isn't either Primary or secondary succession because Primary succession is "newly growth" and secondary succession is "redeveloped habitat".

Answer:

Menstruation, the follicular process, the ovulation and the luteal period are the four stages of the menstrual cycle. Specific menstrual complications include extreme or painful spells and a premenstrual syndrome (PMS). Knowing that a woman is most likely to conceive in the menstrual cycle can increase the chance of pregnancy. in simpler words, Bleeding phase, Pre-fertile phase, Fertile phase, Releasing an egg (ovulation), Post-fertile phase.Estrogen rates increase and fall periodically during the menstrual cycle. Estrogen rates increase during the mid-follicular process, then drop precipitously after ovulation. This is followed by a secondary increase in estrogen levels during the mid-UT phase, with a decrease at the end of the menstrual cycle.Elevated levels of estrogen are a risk factor for breast and ovarian cancer. High levels of estrogen can increase your risk of blood clots and stroke. Estrogen superiority can also improve the risk of developing a thyroid disorder. This may contribute to signs such as exhaustion and increases in weight.

Explanation:

Answer: radio telescopes can be used.

Explanation:

Radio telescopes can be used to see through the dust and the star being born. The stars are born into clouds of gases in the space. Due to gravity more and more gas get collected and it forms a clump. When the clump get big enough the hydrogen atom crash each other to form the helium. The clump of gas becomes a star. The radio telescopes can be used to take pictures of these stars within the clump of gas. It can also be used to take picture of fusion of gases within a star to initiate the formation of new star.

Answer:

It's an infrared telescope.

Explanation:

We can't rely on an optical telescope since it only shows what we can see. In turn, we can use an infrared telescope because it allows us to see heat. We can use this heat to study celestial bodies, stars, and gases.

d) the length of tim that the wind blows

Answer:

In photosynthesis, sunlight is necessary for it allows the plant to synthesize food from the CO2 and water. Without the light, it cannot carry out photosynthesis and create the food to feed itself.  

By keeping some plants in the dark, Sam is removing the ability of the plant to capture light for photosynthesis.

Photosynthesis is a process whereby green plants capture light energy for the synthesis of carbohydrates using inorganic raw materials such as water and carbon dioxide.

The process of photosynthesis takes place in 2 major steps

During light-dependent reaction, energy from light excites chlorophyll molecules and cause an electron to be displaced. The electron in the chlorophyll is replaced by the electron in water, leading to the cleavage of the bond between H and O and the evolution of O2. ATP and NADPH are produced and these are utilized in the light-independent reaction.

In the light-independent reaction, the molecules synthesized from the light-dependent reaction are used to fix carbon dioxide in a series of reactions resulting in the formation of carbohydrates.

Hence, keeping some plants in the dark will alt the light-dependent reaction and the entire photosynthesis process at large.

Answer:

the pleiotropy and epistasis (more info below)

Explanation:

Many human traits have dynamic forms of ancestry. We can be regulated by a single gene with several alleles, or by several genes. Further complication can be added by pleiotropy (one gene, multiple effect) and epistasis (gene-gene interaction). A number of hereditary diseases are triggered by defects in one or a few genes. examples: autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, and mitochondrial.

Answer:

Meiosis

Explanation:

Mitosis and meiosis are both types of cell divisions.

In mitosis, a parent cell undergoes one division and produces an identical, diploid cell. This results in 2 daughter cells.

In meiosis, a parent cell undergoes two divisions. This produces unique, haploid cells. The result is 4 daughter cells that are not identical to the parent cell.

Therefore, the answer is meiosis. Meiosis produces four daughter cells.

Answer: Option A.

. ecological succession, because each community promotes the growth of the succeeding community

Explanation:

Ecological succession is the process in which species structure of an ecological community  changes over  time.

The given example shows ecological succession (secondary succession) as in the image series of community changes over hundred of years including growth of community from bare rocks to trees as each community is promoting growth of succeeding community. But the colonized community of trees after series of changes is disturbed by human activities or natural calamity (as shown in image) reduces an already established ecosystem is called secondary succession (Type of  ecological succession).

Hence, the correct option is a. ecological succession, because each community promotes the growth of the succeeding community

Answer:

Evolution takes the best traits for survival. each new descendant is better adapt to the environment than the previous ancestor.

An ancestor population gets evolved into a descendant species with differences by being separated into two different environments. This environment has varying adaptive traits which cause different changes in each descendant species.

A temporal series of populations or genes which are connected by a continuous line of descent from ancestor is referred to as descendant species.
