According to natural selection theory, Different species occupying the same habitat will adapt to that habitat by undergoing the same genetic changes Adaptations beneficial at one time should generally be beneficial during all other times Well-adapted individuals have more offspring, and thus contribute more to the next generation's gene pool, than do poorly adapted individuals. Adaptations beneficial in one habitat should generally be beneficial in all other habitats

Answers

Answer:

The most correct statement is - Well-adapted individuals leave more offspring, and thus contribute more to the gene pool, than poorly adapted individuals.

Explanation:

Adaption in natural selection is a species, time-specific, and habitat-specific process. So, it means if a species is adapted to genetic changes in a particular habitat, it is not necessary that all other species also adapt to similar genetic changes.

Similarly, if a species has beneficial adaption for a particular habitat, it is not necessary it will be beneficial for the other habitat as well.

Thus, natural selection leads to the well-adapted individual that leave more offspring and contribute more to the gene pool.

Which of the following represents a possible chromosome number of a species that uses sexual reproduction, and why?
A

С
23, because this number will create a diploid cell, the result of both female and male gametes combined.

D
23, because this number will create a haploid cell, allowing both female and male gametes to be combined

Answers

Answer:

B. 62, because this number will create a haploid cell, allowing both female and male gametes to be combined.

Explanation:

Sexual reproduction involves two organisms to come together (male and female). Sexually-reproducing organisms make use of a process called MEIOSIS to produce gametes or sex cells, which have a reduced number of chromosomes as the parent cells producing them.

A sexually reproducing organism must contain a complete diploid chromosome number (2n) that allows it to produce cells with a haploid chromosome number via meiosis. The haploid gamete cells that result from each meiotic divisions of male and female parents can combine to form a whole diploid organism.

The number of a species should be uses se-xual reproduction,

B. 62, because this number will create a haploid cell, allowing both female and male gametes to be combined.

Se-xual reproduction:

It includes the two organisms for come together i.e. male and female. It make use of a process known as MEIOSIS to generate gametes. A se-xually reproducing organism should contain a complete diploid chromosome number (2n) that permits it to generate cells with a haploid chromosome number via meiosis.

Compared to the Sun, the star Betelgeuse is
A. Less luminous and warmer
B. Less luminous and cooler
C. More luminous and warmer
D. More luminous and cooler

Answers

The answer to that is A

Red supergiant star Betelgeuse is around 764 times as massive as the Sun. To put that into perspective, the diameter of Mars' orbit around the Sun is 328 times that of the Sun. Thus, option A is correct.

What is the comparison of Sun and star Betelgeuse?

Betelgeuse is 640 light years away from the sun. Given that the star is only 10 million years old, it will die young like earlier supergiants.

The sun, in contrast, is only approximately halfway through its life and is nearly 4.6 billion years old.

Betelgeuse is one of the gleaming stars in the night sky and can be seen clearly on the right shoulder of the constellation Orion.

Betelgeuse is a red supergiant that is 1,400 times bigger than our Sun and thousands of times brighter.

The broken bone begins to take the shape it had prior to the fracture.

A mass of tissue containing cells that produce collagen fibers forms. These collagen fibers extend across the broken bone and attach the pieces back together.

A hematoma forms at the fractured area.

Osteoblasts and osteoclasts arrive at the fracture and begin to produce bone tissue there.

Answers

Answer:

The correct order is:

1. A hematoma forms at the fractured area.2. A mass of tissue containing cells that produce collagen fibers forms. These collagen fibers extend across the broken bone and attach the pieces back together.3. Osteoblasts and osteoclasts arrive at the fracture and begin to produce bone tissue there.4. The broken bone begins to take the shape it had prior to the fracture.

Explanation:

After the fracture of a bone several events occur that involve the regeneration and remodeling of the broken bone:

Hematoma in the fracture area is produced by the bleeding of the bone marrow, especially when it occurs in long bones. The collagen fibers are intended to initiate the repair process, trying to join the bone fragments that have separated. The purpose of this is to build a soft tissue base on which the new bone will grow. Osteoblasts and osteoclasts are responsible for the process of ossification and remodeling, respectively. Only a bone scar will remain at the fracture site. With the process of ossification and remodeling, the bone acquires the same shape it had before the injury.

This whole process is necessary for the morphological and functional recovery of a bone when it has suffered a fracture.

Answer: 4, 2, 1 , 3   is the order on Edge.

Organic matter is a component of biological relics found in the soil. It makes up a significant portion of the soil.

Soil organic matter should not be confused with biomass production. Rainforest due to its biodiversity is rich in organic biomass. These organic matter decays rapidly due to the humid conditions, and are become lost. Also, the rate of weathering in the rainforest is very high. This often washes and removes organic matter from the soil. These conditions are not so in the temperate forest.
