Answer: Elephants

Explanation:

Elephants have being able to survive in the savannah due to its ability to adapt. Elephants natural have no sweet glands so they have to device other means to cool their selfs, th ey achieve this by flapping their ears to create the cooling effects they need to survive in their environment. They also posses tusk and long trunks which they used for eating and drinking. The adaptation of the elephants to the African savannah has being due to the effects of environment and the genes. A popular example is an African elephant is different from it’s counterpart from Asia. Africa elephants have bigger ears unlike Asians which are smaller

Answer: let's use Zebra's as an example of an Animal living in the Africa Savannah, these animals have adapted to their environment for survival, during shortage of water and food they migrate (moving to another area) and hibernating (to conserve power) until the season is over. They feed on grasses and often use camouflage to protect themselves from predators e.g lions, when they are roaming in the open.

We can say that the adaptation of this Animal depends on both Environmental and genetic factors this is because, they move when there is shortage of food and water which is affected by the environment, and apart from using camouflage for protection, zebras can run fast too, Some even run in a zigzag pattern while being chased, making them even harder to catch which is a genetic factor.

mixer [17]

Answer:

A

Explanation:

According to this hypothesis that pillar coral digested zooxanthellae, the coral digested zooxanthellae inside the pillar coral must be dead. If anything is engulfed then it should be first dead inside the body of the predator and then the energy is extracted from the food. The food eaten serves as a source of energy.

Name two things that increase the amount of nitrogen in the nitrogen cycle
Allushta [10]

The majority of Earth's atmosphere contain 78% is nitrogen, The Nitrogen cycle is the geochemical cycle in which nitrogen is converted into multiple chemical forms. Nitrogen cycle occurs in terrestrial and marine ecosystem. Nitrogen can be converted through both biological and physical process. The processes that are involved in nitrogen cycle are fixation, ammonification, nitrification, and denitrification.

There is limited amount of nitrogen that is useful but <u>increase of fossil fuel combustion, use of artificial nitrogen fertilizer</u> have dramatically increased the amount of nitrogen in nitrogen cycle.

Diseases such as diphtheria result from a process called lysogenic conversion in which viral dna is integrated into a bacterial
bazaltina [42]
<span>The correct answer is horizontal gene transfer, transduction.</span>  

Transduction (a type of horizontal gene transfer)is the process by which foreign DNA is introduced into a bacteria cell. When viruses infect bacterial cells, their DNA is integrated into a bacterial chromosome and thus harness the replicational, transcriptional, and translation machinery of the bacteria. As a result, bacteria cell makes numerous virions (viral particles).

soldier1979 [14.2K]

The question is incomplete as it does not have the options which are:

A) n+1; n+1; n-1; n-1

B) n+1; n-1; n; n

C) n+1; n-1; n-1; n-1

D) n+1; n+1; n; n

Answer:

Option-1

Explanation:

The laws of inheritance were concluded from the result of Mendel's experiment which is based on the fact that gametes are formed. Later research suggested that gametes are formed by the process of meiosis which takes place in two phases and recombination is a characteristic of Meiosis.

If during anaphase I of meiosis I, the alleles fails to separate that is nondisjunction takes place at anaphase I, Then the resulting daughter cells will have unequal distribution of chromosomes.

One daughter cell will receive 1 extra copy of the chromosome while another daughter cell will receive 1 less chromosome therefore ploidy level will be n+1 and n-1.

During meiosis II, 2 more daughter cells will be formed with the same ploidy level therefore in last the meiosis will result in 2 (n+1) and 2 (n-1) cell.

Thus, Option-1 is the correct answer.
