Answer: The amniotic egg was an evolutionary invention that allowed the first reptiles to colonize dry land more than 300 million years ago. Fishes and amphibians must lay their eggs in water and therefore cannot live far from water. ... Within the chorion is the amnion, the membrane for which the amniotic egg is named.

Explanation:

A. Phyletic gradualism isn't supported by the fossil record, but punctuated equilibrium is

Punctuated equilibrium and phyletic gradualism are two opposing evolutionary tendencies that can be seen in the geological record. Species in punctuated equilibrium tend to demonstrate morphological stasis between rapid speciation episodes, whereas species in phyletic gradualism change more frequently. "Phyletic gradualism isn't supported by the fossil record, but punctuated equilibrium is," says the statement that best summarizes the ideas of phyletic gradualism and punctuated equilibrium.

D. A person with a Doctoral Degree in Entomology and a Certificate in Forensic Entomology.

They will know the most about forensic entomology compared to the rest of the options.

A person with a Doctorial Degree in Entomology and a Certificate in Forensic Entomology. Hence option D is correct.

Entomology is defined as the investigation of insects and how they interact with people, the environment, and other living things. Entomology is employed extensively in a wide range of fields, including evolutionary biology and medical research, in addition to studying the anatomy and physiology of insects. It aids agricultural entomologists in their research on biodiversity as well as in the protection of priceless resources from insect pests.

Forensic entomology is defined as the study of arthropods, particularly insects, connected to criminal activity and other judicial issues. An essential tool in the examination of homicide, self harm, and other violent crimes is forensic entomology. When properly gathered and examined by skilled forensic investigators, insect evidence found on a victim's corpse can provide important information.

Thus, a person with a Doctorial Degree in Entomology and a Certificate in Forensic Entomology. Hence option D is correct.

Answer:

C. produced from magma.

D. formed at Earth’s surface

Explanation:

Earth crust refers to the outermost layer or thin shell which makes up the earth such as sedimentary, metamorphic and igneous rocks.

The Earth crust is typically made up of two (2) main types;

1. Oceanic crust: this crust has a thickness ranging from 5 km to 10 km and comprises of denser rocks such as diabase, gabbro and basalt.

2. Continental crust: this crust has a thickness ranging from 30 km to 60 km and comprises of minerals such as quartz, silicate, feldspar, aluminum and less dense rocks such as granite

An igneous rock has a coarse texture and is dark in color. Also, an igneous rock can be accurately described as being produced from magma and formed at Earth’s surface.

D. Viruses can have a lipid envelope derived from the host cell membrane. So they have the same phospholipids and glycoproteins (they also have specific viral proteins)

Answer:

Advantages

- Serial dilution is used in microbiology to estimate the concentration or number of cells/organisms in a sample to obtain an incubated plate with an easily countable number of colonies.

- In biochemistry, serial dilution is used to obtain the desired concentration of reagents and chemicals from a higher concentration.

- In pharmaceutical laboratories, serial dilution is performed to receive the necessary concentration of chemicals and compounds as this method is more effective than individual dilutions.

- In homeopathy, homeopathic dilutions are used where a substance is diluted in distilled water or alcohol. It is believed than dilution increases the potency of the diluted substance by activating its vital energy.

Disadvantages

- An error might occur during the propagation of the sample, and the transfer inaccuracies lead to less accurate and less precise transfer. This results in the highest dilution to have the most inaccuracies and the least accuracy.

- Because serial dilution is performed in a stepwise manner, it requires a more extended period of time which limits the efficiency of the method.

- Serial dilution only allows the reduction of bacteria/cells but not the separation of bacteria/cells like in other techniques like flow cytometry.

- This technique also requires highly trained microbiologists and experts in aseptic techniques.

B. the body's internal environment

Explanation:

Homeostasis is defined as the process of maintaining the internal environment of the body.

All the systems work together to maintain homeostasis. The nervous and endocrine systems are two important system that helps in maintaining homeostasis.

The nervous and endocrine systems are linked with hypothalamus that controls the internal environment of the body by releasing and inhibiting hormones. These hormones keep pH,  temperature,  and other internal conditions stable that support homeostasis.

Hence, the correct answer is "B. the body's internal environment".

Answer:

For example, if a car turns a corner at a constant speed, it is accelerating because its direction is changing. The quicker you turn, the greater the acceleration. So there is an acceleration when velocity changes either in magnitude or in direction, or both.
