Which of these is an example of active transport?
A Glucose molecules move against the concentration gradient across the cell membrane with the help of ATP.
B. Carbon dioxide molecules diffuse freely across the cell membrane.
C. Water molecules move down the concentration gradient across the cell membrane with the help of a channel protein.
D. Oxygen molecules become trapped inside the cell membrane with the help of ATP.
Answer:
a. glucose molecules move agnst the concentration gradient across the cell membrane w the help of atp
Explanation:
active transport requires energy (atp) to push a molecule agnst its concentration gradient
also glucose molecules r too large to cross without the help of transmembrane proteins
and oxygen molecules r able to get thru by simple diffusion bc they r small enough
Glucose molecules move against the concentration gradient across the cell membrane with the help of ATP is an example of active transport.
Active transport is a biological term to refer to the movement within the cell in which some molecules move across the cell membrane. This movement requires energy from cells to move.
According to the above, when a glucose molecule moves against the concentration gradient across the cell membrane and in this movement it consumes energy (ATP) it is carrying out active transport.
According to the above, the correct answer is A. because it exemplifies active transport.

Answer:
Passive transport is a naturally-occurring phenomenon and does not require the cell to exert any of its energy to accomplish the movement. In passive transport, substances move from an area of higher concentration to an area of lower concentration.

Which of the following processes is most likely to occur as a result of an
animal cell receiving a signal to initiate apoptosis?
Answer: lysosomes will release digestive enzymes into the cytosol
Explanation:
Apoptosis is one of the cellular mechanisms of cell death in a controlled manner. At the initiation of apoptosis, the lysosomes start secreting the digestive enzymes in the cytoplasm. Thus, option D is correct.
What is apoptosis?Apoptosis has been defined as programmed cell death in multicellular eukaryotes. It involves biochemical steps that involve cell shrinking, fragmentation of the nucleus, condensation of chromatin structure, decay of the mRNA, and the disintegration of the DNA.
It is a significant process in animal cells as it destroys the unwanted and harmful cancerous cells that can damage the body. They are very crucial in cancer and are initiated by the alteration in the survival signals and sudden dissociations.
The lysosomes play an important role in apoptosis as they're the specialized organs that release digestive enzymes that initiate cell death. They undergo autolysis when the signals for apoptosis are initiated.
Therefore, in option D. the lysosomes are responsible for apoptosis.

1. Explain how the Coriolis effect affects ocean current movements in the northern and
southern hemispheres in your own words.
2. Infer why upwellings are economically important in your own words.
Answer:
Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect. Click the image for a larger view. Coastal currents are affected by local winds.
Upwelling is the process that brings deeper water to the surface, and its major significance is that it brings nutrient -rich deep water to the nutrient-deprived surface, stimulating primary production

B. The passage of a million years
C. An increase in the variety of mammals on Earth
D. The extinction of mammals and the rise of insects as the dominant species
B. Anwar
global warming has a bearing on the planet's biological evolution.
Evolution is the million years old process, which has led to the adaptation and development of a variety of species. The new era of the Earth can be marked by the extinction of mammals and the rise of insects.
The correct option is:
Option D. The extinction of mammals and the rise of insects as the dominant species
The Cretaceous period was ended around 66 million years ago. The sudden asteroid attack on the Earth killed the mass population of mammals and most of all the other species.
Somehow, few of the mammals survived and thrived, which made them dominant across the planet.
In the future, the million years or the hitting of an asteroid can mark the new beginning of an era. The asteroid hitting can lead to the extinction of organisms present on the Earth. Some of the species or insects can survive hypothetically, which can represent the beginning of the new era.
Therefore, the correct option is D.

The molecule BPG binds to the deoxy form of hemoglobin in the central cavity. Explain why that makes sense for oxygen delivery and why BPG is said to stabilize the deoxy state.
Answer:
Oxygen binds with the hemoglobin to carry the blood to different body parts through the circulatory system. The binding of the oxygen to Hb is regulated by the Bisphosphoglycerate or BPG molecule. It is bounded to the deoxy form of hemoglobin.
BPG binds with deoxy Hb in the central cavity of the four subunits which decreases the affinity to hemoglobin. The binding of BPG stabilizes T form or deoxy-Hb as the central cavity is larger in T form in comparison to the R state. R state has a low affinity to oxygen due to relatively smaller central cavity.

Moving up the food chain, the energy available to the organisms decreases due to metabolic heat. (You can add the second law of thermodynamics into it, if you want)
For example, in the rules of tens, the plants start with 100% of the energy but the fi red t level consumers gain 90% of the energy due to the fact energy transfers through heat.
Because of the change is available energy, consumers at the higher levels of the food chain are forced to hunt larger amounts of prey to sub stain themselves.
Where does the energy go?
Answer: energy can travel in the form of electromagnetic waves, heat, light, radio and gamma rays. your body is using energy. Energy is always flowing and changing forms.
