How would you classify corals' role in its community (keystone, dominant, foundation, pioneer, Indicator, or more than one) and
kogti [31]

Answer: Keystone species

Explanation: A keystone species is a species which occupied a niche so central in the ecosystem that it has a disproportionately large effect on its environment and other species in it.

The coral's function in its ecosystem is so vital that if you were to remove it, the entire community would be drastically altered beyond recognition.

The coral serves as the base structure of its ecosystem.

That is to say that many corals are hermatypic(they form reefs). This reef serves as the environmental structure of the Coral's ecosystem. Built in and around it is a very biodiverse biotic environment. The coral not only serves as a hiding place and habitat for many marine organisms including fish, clams, lobsters, etc. It serves as resting place for larger animals like turtles and also serves as hunting sites for other animal species.

The most common way of determining a keystone species, is to see what happens when that species is removed from the ecosystem. Coral have shown to be so central to their ecosystem that the bleaching of coral reefs due to tourism and climate change causes a massive loss to biodiversity. And this is quite significant as reefs are the most biodiverse marine habitats.

In humans, MN blood types are determined by an autosomal gene with two alleles: LM and LN. In one population of 592 people, ther
RoseWind [281]

Answer:

148

Explanation:

According to Hardy-Weinberg equilibrium,

p + q = 1

p² + 2pq + q² = 1 where,

p = frequency of dominant allele

q = frequency of recessive allele

p² = frequency of homozygous dominant genotype

2pq = frequency of heterozygous genotype

q² = frequency of homozygous recessive genotype

Here,

Total population = 592

Number of NN people = 148

Frequency of N blood group or NN genotype (q²) = 148/592 = 0.25

q = √0.25 = 0.5

p = 1 - q

= 1 - 0.5 = 0.5

Hence, p = 0.5

Frequency of MM genotype = p² = 0.25

Number of people with MM genotype = 0.25*592 = 148

Hence, 148 people will have MM genotype or M blood group.

The uterine phase where the thickness of the endometrium doubles is the
andrey2020 [161]

Answer:

Proliferative phase

Explanation:

Uterine cycle is part of the menstrual cycle in which changes occur in the reproductve female system in order to prepare female on possible pregnacy. Uterine cycle isdivided into three phases:

  1. Menstrual phase-characterized by the process of menstruation
  2. Proliferative phase-estogen causes the production of new endomethrium layer (thickening of the endomethrium)
  3. Secretory phase-characterized by the production of progesteron which prepares endomethrium for the implementation.

Muscular exercise presents a dramatic test of the body's homeostatic control systems because it results in large _____.
kicyunya [14]

Muscular exercise presents a dramatic test of the body's homeostatic control systems because it results in large amounts of heat production.

Homeostatic control systems- A body's physiological ability to maintain a steady internal environment in response to changes in the external environment is known as homeostasis.

Heat Production- The term "thermogenesis" refers to the process through which energy is lost by producing heat with specialization.

Energy- In biology, cells frequently store energy in macromolecules, especially lipids and carbohydrates (sugars). When chemical bonds are formed, such as during the redox reactions of cellular aerobic respiration, energy is released.

Redox Reactions- A reaction that happens when an oxidizing material and a reducing substance come into contact.
