Life as a hunter? Who <br> May be the lions main competitors

Stolb23 [73]

Lions compete with animals such as hyenas, cheetahs and wild dogs. Cheetahs are better hunters than lions, faster and better withstand the heat. Hyenas, as they have a larger pack, scare away lionesses after hunting and appropriate the meal.

<h3>What kind of relationship exists between the lion and the hyena?</h3>

The relationship of commensalism is established because hyenas have scavenger habits, that is, they feed on mortal remains left by other animals, in this case, the lion. In this way, the lion hunts its prey and feeds, and what remains is consumed by the hyenas.

With this information, we can conclude that Competition is a disharmonious or negative ecological relationship, in which interaction occurs between individuals looking for the same resource, usually when there is a scarcity of that resource.Lions rule the savanna kingdom and are taught to hate hyenas, who compete for the same resources.

What does the determination of sex (in humans) have to do with meiosis?

Allisa [31]

Answer:

In humans and other mammals, biological sex is determined by a pair of sex chromosomes: XY in males and XX in females. Genes on the X chromosome are said to be X-linked. X-linked genes have distinctive inheritance patterns because they are present in different numbers in females (XX) and males (XY).

If a DNA strand has 32 % guanine, what percent thymine does it contain?

Alex_Xolod [135]

Answer:

B

Explanation:

Guanine and Cytosine pair together. So, if 32 percent is guanine, then 32 percent should also be cytosine. This is a total of 64 percent. The remaining 36 percent is split between thymine and adenine. So, Thymine will have half of 36 percent which is 18 percent.

What term is used to describe bacterial cells that can naturally take up dna from their environment?

Maru [420]

<h2>The correct answer is: Competent cells</h2>

Explanation:

Bacterial cells have the capability of incorporating foreign naked DNA or deoxyribonucleic acid fragments from the environment or the exterior of the cell to the interior of the cell. This process is known as Transformation.
The bacterial cells which are able to undergo transformation are called Competent bacterial cells.
Some of the bacterial cells are naturally competent like<em> Bacillus subtilis, Streptocossus pneumoniae</em> while others like <em>Escherishia coli </em>need to be chemically treated to make them artificially competent.
In natural competence, the foreign DNA from the cell exterior is incorporated into the cell interior through specific protein complexes present in the plasma membrane of the bacterial cells.
In artificial competence, the negative charge on foreign DNA is masked by positively charged calcium ions (so that it is not repelled by the negative charge of the lipid bilayer of the bacterial cell plasma membrane) and then small pores are created in the lipid bilayer of the plasma membrane of the bacterial cells by giving a heat shock to the cells. This results in the uptake of the DNA by the bacterial cells.
