To measure a population’s baseline genetic state, it must have _____________ to be in Hardy-Weinberg equilibrium.

A) Gene Flow

B) Random Mating

C) Selection

D) Mutations

Answers

Answer:

Random mating

hope it helps!

There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change).

To measure a population’s baseline genetic state, it must have random mating to be in Hardy-Weinberg equilibrium (Option B).

The Hardy-Weinberg principle state that the genetic variation in a population will remain constant across generations in the absence of different evolutionary forces.

The Hardy-Weinberg assumptions include random mating, no mutation, no gene flow, infinite population size, and absence of selection.

In consequence, random mating acts to prevent any change in the allele frequencies.

In conclusion, to measure a population’s baseline genetic state, it must have random mating to be in Hardy-Weinberg equilibrium (Option B).

7. (True Story) In Denmark, a husband and wife who had been unsuccessfully trying to have a
baby went to a fertility clinic. Sperm and eggs were collected from father and mother, and
combined in a petri dish, creating several "test-tube babies". These babies were implanted in the
mother and 9 months later she ſlelivered twins, one with lightly pigmented skin and one with
darkly pigmented skin. Because this seemed strange, a DNA test was conducted and it was
found that both children were related to the mother, but only the light skinned child was related to
the father. How can this be explained? (Hint, there was no infidelity)

Answers

Answer:a

a possible explanation for this occurrence is that a test tube or dropper was accidentally used repeatedly without being sterilized, causing sample cross-contamination. DNA in this test case did not confirm that the father of the second child was another client of the fertility clinic who had never met the mother...therefore this is a possibility.

Answers

Answer:

1. Notochord.

2. Dorsal hollow nerve cord.

3. Pharyngeal slits.

4. Pharyngeal slits.

5. Notochord.

6. Dorsal hollow nerve cord.

Explanation:

A living system can be defined as the internal systems found within living organisms and how different materials circulate within these organisms.

Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, circulatory system, and digestive system.

A chordate can be defined as an animal found in phylum chordata of the animal kingdom such as vertebrates, cephalochordates, tunicates, etc.

The four (4) shared anatomical features or characteristics of chordates includes the following;

1. Notochord: found between the digestive tract and nerve cord.

2. Dorsal hollow nerve cord: in some embryos this develops into the central nervous system.

3. Pharyngeal slits: in invertebrate chordates can be involved in filtering food from water ingest through the mouth.

4. Pharyngeal slits: in jawed fish this provides support for the jaw.

5. Notochord: provides skeletal support.

6. Dorsal hollow nerve cord: is derived from the ectoderm.

10 pounds of seal for a killer whale to gain one pound (10:1). how many pounds of seal will it have to eat to gain 20 pounds of killer whale?

Answers

Answer:

200

Explanation:

20 times 10 is 200 easy

Answer:

200

Explanation:

Multiply 10 by 20 and you'll get 200.

10 pounds = 1 pound gained

? = 20 pound gained

10 : 1

? : 20

1 x 10 = 10

20 x 10 = 200

Hence, the killer whale will have to eat 200 pounds of seal to gain 20 pounds.

Anything that contains atoms emits infrared radiation. Therefore, option (D) is correct.

What is Infrared radiation?

All objects, living or non-living, emit some amount of infrared radiation, which is a type of electromagnetic radiation with wavelengths longer than those of visible light. The amount and wavelength of the infrared radiation emitted by an object depends on its temperature, with hotter objects emitting more and shorter-wavelength infrared radiation.

This is the principle behind the use of infrared cameras and thermal imaging technology to detect and measure heat in a variety of applications, including night vision, medical imaging, and industrial inspections.

Answers

1Answer:

The correct answer is - D. how changes in biodiversity impact an ecosystem.

Explanation:

The water hyacinth is an invasive plant species that rapidly grows and creates a thick layer over the water surface in almost every aquatic ecosystem. The growth of the layer of this species causes problems to the environment, ecosystem, humans, and other species.

These aquatic plants reduce the oxygen level and other nutrients from the ecosystem it is introduced and affect the biodiversity by increasing heavy metals and contaminants.

The layer of this plant inhibits photosynthesis that decreases sugar and energy production and blocks the boat and ship movements and economically as well.
