Answer:
The Cell Cycle | Back to Top
Despite differences between prokaryotes and eukaryotes, there are several common features in their cell division processes. Replication of the DNA must occur. Segregation of the "original" and its "replica" follow. Cytokinesis ends the cell division process. Whether the cell was eukaryotic or prokaryotic, these basic events must occur.
Cytokinesis is the process where one cell splits off from its sister cell. It usually occurs after cell division. The Cell Cycle is the sequence of growth, DNA replication, growth and cell division that all cells go through. Beginning after cytokinesis, the daughter cells are quite small and low on ATP. They acquire ATP and increase in size during the G1 phase of Interphase. Most cells are observed in Interphase, the longest part of the cell cycle. After acquiring sufficient size and ATP, the cells then undergo DNA Synthesis (replication of the original DNA molecules, making identical copies, one "new molecule" eventually destined for each new cell) which occurs during the S phase. Since the formation of new DNA is an energy draining process, the cell undergoes a second growth and energy acquisition stage, the G2 phase. The energy acquired during G2 is used in cell division (in this case mitosis).

Which of the following is NOT an example of
a convergent boundary?
A. continental crust to continental crust collision
B. mantle to core collision
C. continental crust to oceanic crust collision
D. oceanic crust to oceanic crust collision
Mantle to core collision is NOT an example of a convergent boundary. Therefore option B is correct.
Convergent boundaries are places where tectonic plates move toward each other. When they collide, various geologic processes occur.
However, option B, "mantle to core collision," is not an example of a convergent boundary. The mantle and core are both parts of the Earth's interior, and there is no boundary between them where tectonic plates interact.
The other options (A, C, and D) involve interactions between different types of tectonic plates at convergent boundaries, such as continental crust colliding with other continental crust (A), continental crust with oceanic crust (C), and oceanic crust with oceanic crust (D).
These interactions often result in significant geological phenomena like mountain formation, subduction zones, and volcanic activity.
Therefore option B mantle to core collision is correct.

9.If you break an atom apart would it still behave like the element that makes it up? (yes/no)
Answer:
Yes.
Explanation:
The energy released in splitting just one atom is miniscule. However, when the nucleus is split under the right conditions, some stray neutrons are also released and these can then go on to split more atoms, releasing more energy and more neutrons, causing a chain reaction.

If humans have altered the natural environment, describe the changes made by humans and their impact on the species.
Answer: The changes that humans have made are the changes to the atmosphere. That is the most significant change. The burning of fossil fuels increases the Co2 levels in the atmosphere along with other greenhouse gases such as methane. This causes the temperature to rise because the heat waves are stuck in the layer. The PH levels continue to rise in the oceans due to climate change also.

A student put some drops of lugols iodine solution into the water in the beaker shown to the right the water turned red after a short time the starch solution inside the dialysis tube and turn the black what function of the cell membrane was a student demonstrating
Answer:
diffusion through a selectively permeable membrane
Explanation:
The cell membrane selectively allows certain substances to enter or leave a cell . This implies that cell membranes are selectively permeable; they allow some substances to pass through, but not others.
Direct transport of materials across the cell membrane is often passive. Passive transport does not require energy to occur. Passive transport is the movement of substances from a region of higher concentration to a region of lower concentration. A concentration gradient is always required.
The diffusion through a selectively permeable membrane is an example of passive transport.
The iodine moves into the dialysis tube across the semi permeable cell membrane from a region of higher concentration to a region of lower concentration in response to a concentration gradient.

Why are seeds an evolutionary advantage for seed plants?
Seeds allow for the transport of water and nutrients.
Seeds develop into adults without sexual reproduction.
Seeds protect and nourish young, growing plants.
Seeds provide the materials for photosynthesis.
Answer:
Seeds protect and nourish young, growing plants.
Explanation:
Seeds allow for young plants to be protected in the hard case of the seed.
Seeds also contain a food supply that allows for the young plants to be nourished.
So, seeds are an evolutionary advantage for plants because they protect and nourish growing plants.
The reason why seeds are an evolutionary advantage for seed plants is because: C. Seeds protect and nourish young, growing plants.
What is an evolution?Evolution can be defined as a process of gradual change in the characteristics and genetic pool (make-up) of the species of a living organism over several generations.
What is a seed?A seed refers an embryonic plant or a fertilized ovule which contains the plant embryo that are generally enclosed in a protective outer covering and are used for plant reproduction.

Why is there an increase in the number of people infected with the disease despite the increase in the number of vaccinated?
Answer:
Some people refuse to take the vaccine. a person who carries or has the virus can infect hundreds of people. Therefore the few people who don't take vaccines give it to others. Also, people with the vaccine can still get corona. Most people have stopped wearing masks once they get the vaccine so they are at high risk too.

Identify the highlighted muscle.
Answer:
Brachialis
Explanation:
The Brachialis is an anterior skeletal arm muscle that extends from the medial arm to the superior area of the forearm. The brachialis fibers originate in the anterior part of the humerus and direct to the inferior part of the elbow, where they insert in the upper region of the ulna and distal radius. This muscle is an elbow flexor being used in every movement needed to approximate the anterior part of the forearm to the arm. It is a very thick and powerful muscle that acts with high speed.
The upper limb or arm is the functional unit of the human body, which is made up of 6 different muscular regions, such as the pectoral, upper arm, hand, posterior forearm, and anterior forearm.
In the given image of the upper extremity, the muscle highlighted is the brachialis.
Brachialis anticus or the Teichmann's muscle is present in the upper extremity, which helps in the flexion of the elbow. The muscle is situated in the deeper biceps brachii and makes up the floor region of the elbow pit.
The muscle originates in the anterior part of the humerus and directs the inferior of the elbow. The brachialis muscle is one of the largest flexors of the elbow, which provides the movement or flexion of the forearm at the elbow.
Therefore, the given image is of the brachialis muscle.

Suppose that a rabbit breeder notices two individuals in a litter with large, round noses and names this trait the clown trait. He obtains another rabbit that has a long, thin nose and names it the Pinocchio trait. After breeding the rabbits with unusual nose shapes to wildâtype individuals for several generations, he decides to cross rabbits from families with a history of the clown and Pinocchio traits. The first litter from this cross results in individuals of four phenotypes. The phenotypes are clown, Pinocchio, wildâtype, and heartâshaped noses. The pedigree illustrates the inheritance of these traits. Individuals 1 and 4 are siblings and are known to come from a true-breeding wild type line.
1. What is the most likely mode of inheritance for the clown nose?
a. -linked
b. X-linked dominant
c. X-linked recessive
d. Autosomal dominant
e. Autosomal recessive
2. What is the most likely mode of inheritance for the Pinocchio nose?
1. Sex-influence
2. X-linked dominant
3. X-linked recessive
4. Autosomal dominant
5. Autosomal recessive
Answer:
1. The probable method of inheritance for the nose is a male chromosome-linked recessive.
2. The probable method of inheritance for the Pinocchio nose is in the autosomal chromosomes, with a dominance factor.
Explanation:
1. The gene is observed to be expressed in males.
2. The gene of Pinocchio expression has been expressed from the parents with equal phenotype.
