Qil: Which of the following best explains why both plant and animal cells contain cell membranes? A Both animal and plant cells have cell membranes to act as the site of protein synthesis. B Both animal and plant cells have selectively permeable cell membranes to control which substances can enter and leave the cell. C Both animal and plant cells have cell membranes to store and organize their genetic material. D Both animal and plant cells have cell membranes that contain cellulose to provide structure and support for the cell. E This is incorrect; only animal cells have cell membranes.​

Answers

Answer 1
B. Only the plant cell wall is impermeable.
Protein synthesis is undergone in the nucleus and endoplasmic reticulum.
Nucleus is where genetic materials (DNA) are stored and organised.
Only plant cell wall is made up of cellulose. It helps plant cells stay rigid.
Plant cells have both cell wall and cell membrane.

Younger fossils are often morphologically different from older fossils in a lineage. How do paleontologists think the morphological transition happened

Answers

Answer:

Paleontologists thinks that the younger fossils are a species that underwent an-agenesis, gradually evolving a new morphology or/and the younger fossils are a new species that branched off the older one, rapidly evolving a new morphology.

Explanation:

Fossils are the safeguarded remains or hints of creatures, plants, and different life forms from an earlier time. Fossils range in age from 10,000 to 3.48 billion years of age. The perception that specific fossils were related with certain stone layers drove nineteenth century geologists to perceive a land timescale. Like surviving life forms, fossils differ in size from minuscule, similar to single-celled microscopic organisms, to monstrous, similar to dinosaurs and trees.

Fossils give strong proof that living beings from the past are not equivalent to those discovered today; fossils show a movement of advancement. Fossils, alongside the similar life systems of present-day life forms, comprise the morphological, or anatomical, record.

By contrasting the life structures of both present day and terminated species, paleontologists can deduce the ancestries of those species. This methodology is best for life forms that had hard body parts, for example, shells, bones or teeth. The subsequent fossil record recounts the account of the past and shows the development of structure more than a great many years.

4. When an earthquake occurs, where would shaking be greater? Near the epicenter or away
from the epicenter?​

Answers

Answer:

The point at the Earth's surface directly above the focus is called the epicenter of the earthquake. At the epicenter, the strongest shaking occurs during an earthquake. Sometimes the ground surface breaks along the fault. Sometimes the movement is deep underground and the surface does not break.Apr

Explanation:

When an earthquake occurs greater shaking appears near the epicenter.  

• When two blocks of the Earth suddenly slip past one another the phenomenon that takes place is termed as an earthquake.  

• The earthquake occurs when large blocks of the Earth's crust suddenly move past one another at a fault.  

• Earthquakes releases energy which results in the shaking of the ground surface.  

• The location within the Earth where the beginning of Earthquake takes place is known as the hypocenter or focus.  

• The point directly above the focus at the surface of the Earth is known as the epicenter of the Earthquake.  

At the epicenter and close to it, strongest shaking takes place when an earthquake occurs.  

• The severity of the earthquake can be expressed in terms of both magnitude and intensity.  

• Intensity is based on the observed influences of ground shaking on buildings, people, and natural things. It changes from place to place within the region of the earthquake based on the location of the observer with respect to the epicenter of the earthquake.  

Thus, near the epicenter greater shaking will be observed when earthquake takes place.

Which sequence best describes apoptosis at the G1 checkpoint?

Answers

Answer:

The correct answer is "Cdk/cyclin complex is inhibited→ p53 levels rise → p21 production increase".

Explanation:

The missing options of this question are:

A. p53 levels rise → p21 production increase → Cdk/cyclin complex is inhibited

B. p21 production increase → Cdk/cyclin complex is inhibited→ p53 levels rise

C. Cdk/cyclin complex is inhibited→ p21 production increase → p53 levels rise

D. Cdk/cyclin complex is inhibited→ p53 levels rise → p21 production increase

E. p53 levels rise → Cdk/cyclin complex is inhibited→ p21 production increase

The correct answer is option D. "Cdk/cyclin complex is inhibited→ p53 levels rise → p21 production increase".

Apoptosis is a process at which the cells undergo a programmed death. This mechanisms happens at G1 checkpoint first by the inhibition of Cdk/cyclin complex which causes p53 levels to rise and later, an increment of p21 production. First, a cyclin-dependent kinase inhibitor regulates the inhibition of the Cdk/cyclin complex. This causes p53 levels to rise, since p53 is a direct downstream kinase substrate for CDK. Subsequently, p21 production increase as well since p21 is a inhibitor of cyclin-dependent kinases.

The NADH and FADH2 used by the electron transport chain are normally produced in the mitochondria; however. Select one:

a. NADH is also produced during glycolysis in the cytoplasm.
b. NADH is only produced and used in the mitochondria; FADH2 can be used elsewhere.
c. FADH2 is also produced by the citric acid cycle; NADH is not.
d. FADH2 produced in the mitochondria has more energy than does NADH.

Answers

Answer:

The correct answer is option A (NADH is also produced during glycolysis in the cytoplasm).

Explanation:

NADH is NAD + hydrogen, which is among the list of chemicals that produce energy for the body. It's among the vitamins that act as fuel for electrons during cellular respiration. NADH makes more ATP than FADH2  producing water during the electron transport chain.

During the electron transport chain, which is a step in aerobic respiration, both NADH and FADH2 supplies the much-needed H for the formation of ATP.

Glycolysis, which leads to the formation of ATP occurs in the cytoplasm gives energy for metabolism in the cells after is being broken down produces NADH.

In fruit flies, curved wings are recessive to straight wings, and ebony body is recessive to gray body. A cross was made between true-breeding flies with curved wings and gray bodies to flies with true-breeding straight wings and ebony bodies. The F1 offspring were then mated to flies with curved wings and ebony bodies to produce an F2 generation.
1. Diagram the genotypes of this cross, starting with the parental generation and ending with the F2 generation.
2. What are the predicted phenotypic ratios of this F2 generation?
3. Suppose the following data were obtained for this F2 generation:
114 curved wings, ebony body
105 curved wings, gray body
111 straight wings, gray body
114 straight wings, ebony body
Conduct a chi-square analysis to determine if the experimental data are consistent with the expected outcome based on Mendel's laws.

Answers

Answer:

Population of F2 generation will be formed on 9:3:3:1 ratio.

Explanation:

The predicted phenotypic ratios of F2 generation is 9:3:3:1. Ratio 9 represents straight wings, gray body which are dominant allele, ratio 3 represents hybrid flies having curved wings, gray body, ratio 3 represents hybrid flies having curved wings, ebony body and ratio 1 indicates flies with curved wings, ebony body. The population of F2 generation will be formed on the above ratio.

The study of genes is called genetics.

The correct answer is Population of the F2 generation will be formed on the 9:3:3:1 ratio.

What prevents acetylcholine from accumulating in the neuromuscular junction and causing a sustained contraction in a normal individual

Answers

Answer:

Botulinum toxin

Explanation:

Botulinum toxin is known to hinder the release of acetylcholine into the synaptic cleft at the neuromuscular junction.

This leads to acetylcholine not attaching to its receptors and eventually leading to the inability to have muscle contractions.

Hence, in this case, the correct answer is Botulinum toxin prevents acetylcholine from accumulating in the neuromuscular junction in individuals.

If a DNA molecule has 24% adenine, what is the percentage of guanine in the same DNA molecule?
A. 52%
B. 24 %
C. 48 %
D. 26%
I need help plzz

Answers

Answer:

26%

Explanation:

Adenine pairs with thymine.

Guanine pairs with cytosine.

If 24% of the DNA molecule is adenine, that means that there is 24% thymine. This is because they pair together so they have to be equal. That is 48% of the DNA molecule. To find the percentage of guanine, we need to minus 48% from the total 100%.

100 - 48 = 52

Then divide by 2 because you have guanine AND cytosine.

52/2 = 26

Therefore, your final answer is 26% of guanine is in the DNA molecule.
