The study of developmental biology has been found to show that the closely related species show similarities in embryos. Thus, the correct option is A.
What is Developmental biology?Developmental biology is the branch of science which deals with the study of the process through which an organism such as an animal and a plant grows through and develops with respect to time to more evolved organisms.
Developmental biology includes the biology of regeneration, asexual reproduction of an organism, metamorphosis, and also the growth and differentiation of the stem cells which take place in the adult organisms.
Development of species accomplishes two major objectives which generates cellular diversity as well as the order within each generation, and it also ensures the continuity of life from one generation to the next generation.
Therefore, the correct option is A.

1. What is an axis of rotation? Where is Earth's axis of rotation?
Answer The earth rotates around its vertical axis. The axis is an imaginary line passing through the centre of the earth. Its two ends on the surface are called North and South poles The Earth completes one rotation in 24 hours.
2:The Earth's axis is vertical, meaning it runs up and down. (A rolling log, on the other hand, has a horizontal axis, meaning it runs sideways.) The Earth's axis runs from the North Pole to the South Pole. It takes the Earth 24 hours, or one day, to make one complete rotation around this invisible line: Earth's rotation is the rotation of planet Earth around its own axis. Earth rotates eastward, in prograde motion. As viewed from the north pole star Polaris, Earth turns counterclockwise. ... The South Pole is the other point where Earth's axis of rotation intersects its surface, in Antarctica.

Enzymes catalyze chemical reactions in the human body. Which statement best describes how enzymes work?
A They speed up chemical reactions by increasing the activation energy.
B They slow down chemical reactions by increasing the activation energy.
C They speed up chemical reactions by lowering the activation energy.
D They slow down chemical reactions by lowering the activation energy.
Answer:
A
Explanation:
Hope this is helpful!!:)
Enzymes work by speeding up chemical reactions through the lowering of the activation energy of the reactants.
In every reaction, reactants need to summon a minimum energy amount before they can get to products. this energy is referred to as activation energy.
When an enzyme is introduced into a reaction, it lowers the activation energy. By doing so, reactants can get to products quicker because the mountain they need to climb has been lowered by the enzyme.
In other words, enzymes create a shorter route for reactants to take towards their destination - products.

7. If the diameter of the field of view when using the 4x objective is 3 mm, what is the area of the field of view when using the 4X, 10X, and 40X objectives
Answer:
Using 4X view =
1.767 x 4 = 7.068mm
Using 10X view
1.767 x 10 = 17.67mm
Using 40X view
1.767 x 40 = 70.68mm.
Explanation:
If the diameter when using 4x objective = 3mm
then the original diameter = 3/4 = 0.75 mm
The diameter of the field is 0.75 mm
Area of a circle = pie/4 x diameter square
pie = 22/7 or 3.14
diameter = 0.75
The area of the field
3.14 x 0.75 2 =
3.14 x 0.5625=
1.767mm.
The original area of the field = 1.767mm
Using 4X view =
1.767 x 4 = 7.068mm
Using 10X view
1.767 x 10 = 17.67mm
Using 40X view
1.767 x 40 = 70.68mm.

Categorize the following situation as either a pre- or postzygotic isolating mechanism and then specify which type of pre- or postzygotic isolating mechanism it is.
A short hike through the Sandia Mountains from early spring to late summer will often reveal several different species of penstemon. The Rocky Mountain Penstemon blooms in the spring while the very similar inflated penstemon blooms in late summer. As a result, hybrids are rarely encountered.
Answer:
pre-zygotic isolating mechanismType: seasonal or temporalExplanation:
There are different mechanisms of reproductive isolation. These are barriers that inhibit or interrupt the genetic flux between different species. These mechanisms are about the biological characters of each species that prevent the reproduction with other species.
The reproductive isolation mechanisms might be either prezygotic or postzygotic.
Pre-copulatory or pre-zygotic: Ecological or due to habitat isolation; seasonal or temporal; Sexual or ethologic; Mechanical; Gamete incompatibility.2. Post-copulatory o post-zygotic:
Hybrid inviabilityHybrid sterilityHybrid with diminished viability and or fertilityCytoplasmatic interactions.The exposed situation is an example of prezygotic isolation due to seasonal or temporal barriers. Penstemon blooms in the spring, while the very similar inflated penstemon blooms in late summer. Probably, if they had the same reproductive season, they would produce hybrids. But as they are isolated by different reproductive seasons, they do not. As they can not even fertilize, they are considered to be prezygotic isolated species.

1. Using what you have learned about Darwin's Evidence, which statement is true regarding the pictures above?
A. All organisms are of the same species
B. Fish embryos take a long time to develop because they change so dramatically as they develop.
C. Because the embryos all began to develop similarly, this could suggest that there was a common ancestor.
Answer:
I believe: C."Because the embryos all began to develop similarly, this could suggest a common ancestor." would be the best fitting of the current answer choices.
Explanation:
Process of elimination.
We know that organisms of the same species would all look essentially the same, and we know from the second image that they are nowhere near the same species.
Fish Embryos don't really have much to do with this overall, with the majority of the Embryos being from Mammals.
That leaves option C.

What are adaptations and give an example.
Answer:An adaptation can also be behavioral, affecting the way an organism responds to its environment.
Explanation:
An example of a structural adaptation is the way some plants have adapted to life in dry, hot deserts. Plants called succulents have adapted to this climate by storing water in their short, thick stems and leaves.
Water is a renewable resource that is constantly generated through the water cycle. The ocean contains most of the Earth's available water, but it is undrinkable because it contains salt. All but one of the reasons listed are reasons why desalination is not a popular option to have clean, drinkable water. it is expensive to desalinate water. B It could possibly affect the marine ecosystems. Transporting the water to water scarce regions is difficult. D) Since evaporation is involved in deselination, the drinking water is too hot for consumption.

How could plants living in an industrial area be affected by smog?
Answer: The ground level ozone present in the smog also inhibits plant growth and causes immense damage to crops and forests. ... The smog results in mortifying impacts on the environment by killing innumerable animal species and green life as these take time to adapt to breathing and surviving in such toxic environments.
Explanation:
A type of air pollution in which the fog and smoke get mixed in the atmospheric air is called smog. It causes opacity and odour in the environment.
Smog is released from the factory that contains carbon dioxide, sulfur dioxide and smoke from the outlets.
Smog blocks the sunlight and the chemical released goes into the root system of plants interfering with the plant metabolic processes.
This causes damages to the leaves of plants and inhibits the plant process.
Therefore, smog from industries kills the plant.

Which stage of the cell cycle lasts longest?
Answer: i think the Interphase because
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter- means between, so interphase takes place between one mitotic (M) phase and the next.

1. The St. Lucie River drains Lake Okeechobee into the Atlantic Ocean.
What is the relationship among the parts of this system?
Answer:
The St Lucie canal serves as an outlet of drainage for the Okeechobee Lake through the St Lucie River and out to the Atlantic Ocean.
Explanation:
The St. Lucie River is an estuary in Florida, in the United States. It was basically a freshwater system before an inlet was dug to provide access directly to the Atlantic Ocean.
Lake Okeechobee is the second largest freshwater lake in the United States. Water flows into the lake from various sources with Kissimmee River being the major source.
Because of the high levels of water in Lake Okeechobee, the St. Lucie canal was constructed in the 1920s. The St. Lucie canal provides a good outlet from the Okeechobee lake, through the St. Lucie River and out to the Atlantic Ocean.
Why are sex-linked disorders
more common in males?
A. Sex-linked disorders are more common in
females.
B. Males only need to inherit one copy of the
allele.
C. Sex-linked disorders are dominant.
Answer: B
Explanation:
Sex linked disorders are on the X chromosome and males have only 1
It is less common in females because they have 2 X chromosomes
Answer: B
Explanation: Men only have to inherit one copy of the disorder in order to have it since they’re XY and females are XX. With females, they could get another dominate trait to prevent them from having the disorder (they would then be a carrier) but with males there’s not any way to block it out.

Yes
Or
Not yet
Explain
The planet earth being a terrestrial planet is made up of rocks and hard rigid slabs of rocks called plates. These plates float on the flexible (asthenosphere) Mantel.
I understand that earth is a rocks planet and is made up of rocks and these rocks are called plates.
This uppermost layer or the crust of the lithosphere is composed of SIAL that is rocks made from aluminum and silicon, oxygen components. The layer lying below this is made from the semi-fluid matter called as upper mantel that is the asthenosphere which is partly molten and is said as molten rock. Due to the less dynamicity of this layer the above crust floats or drifts.Hence the water and soil in the lithosphere are characteristic of the crustal rocks.
