Explanation:

Because each chromosome is made from a single molecule of 'DNA', before a cell divides itself, it had to replicate and copy its DNA. This makes it so that after cell division, each new cell holds an exact copy of the genetic material from the original cell.

Answer:

to propel itself through its environment and to attach itself to a variety of structures

Explanation:

I took the quiz(-.-)

Rotifers foot is transformed into a variety of structure for moving and swimming and attach itself to a different structure, hence option d is correct.

Some rotifers are really planktonic and free-swimming, while others travel around a substrate via inchworming, and some are sessile and reside inside tubes or gelatinous holdfasts.

About 25 species are sessile or planktonic, colonial (such as Sinantherina semibullata), and some rotifer species have evolved four moveable toes that are equipped with pedal glands to facilitate swimming and crawling.

Rotifers swiftly colonize new environments and transform primary production (algae and cyanobacteria) into a form that is secondary consumers.

Therefore foot of the rotifers is changed into a different structure for movement is attach itself to a variety of structures, hence option d is correct.

Answer:

vulnerable would be the answer

Currently, there are more than 1,300 species in the US that are either endangered or threatened. Species that are in risk of going extinct include those plants and animals that have become so scarce.

A species that is endangered is one that is in danger of going extinct. The two main factors that cause a species to become endangered are habitat loss and genetic diversity loss.

Natural occurrences may result in habitat loss. For instance, dinosaurs had their home removed some 65 million years ago.

A species that has been designated as vulnerable by the IUCN is one that is predicted to go extinct unless the conditions that jeopardize its existence and reproduction change.

Therefore, A species that is naturally rare or that has been depleted to dangerous levels is known, according to the Endangered Species Act, as a(n)(vulnerable) species.

Answer:

Anything that is currently moving or giving off energy such as heat, light, or magnetism would be kinetic energy instead.

Explanation:

Things like objects on top of hills, unused batteries, chemicals that haven't been mixed, would all be examples of potential energy. Even steam is an example of potential energy since it has changed to a higher energy state. But as soon as steam does something, causes an injury (scalding), or starts to turn back into water, then it is kinetic energy.

Of course, to blur the lines a bit, something can have both forms of energy at the same time. If you push a cart down a hill, the movement is the kinetic energy, but until it reaches the bottom, then it also has potential energy in the form of gravity.

Kinetic energy and thermal energy are two non-examples of potential energy as they are forms of energy related to motion and particle movement, respectively, rather than stored energy.

Kinetic energy is not an example of potential energy as it is the energy of an object in motion, while thermal energy is also related to the random motion and vibrations of particles rather than stored energy based on position or configuration.

Kinetic Energy: Kinetic energy is the energy possessed by an object due to its motion

Thermal Energy: Thermal energy is the energy associated with the random motion of particles within a substance.

Thus, kinetic and potential energy are examples of non-potential energy.

Answer:

When a stimulus is detected by a sensory receptor, it can elicit a reflex via stimulus transduction.

Answer:

the first blank is biodiversity. I think like that

The place where a group of organisms lives is called the habitat. The combination of the community and habitat is called the ecosystem.

An ecosystem is basically the neighborhood where animal lives. The habitat is the animal's address in that neighborhood. Some animals can survive in more than one habitat. Other animals are limited to certain habitats. For example, moose habitat is more specific than gray squirrel habit.

Moreover, ecosystem is defined as the interrelationships between the biotic and abiotic component of the environment. Whereas habitat is defined as the natural environment in which a particular species of plants and animals lives.

Therefore, a habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive. For an animal, that means everything it needs to find and gather food, select a mate, and successfully reproduce.

1. generation or birth or gender) is a basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein.

2: 1. Body cells make up the body of any multicellular organism. On the other hand, a gamete is a sex cell that can either be a sperm or egg cell.

2. Body cells undergo the process of mitosis while gametes undergo a process called meiosis.

3. A body cell contains a complete number of chromosomes and is called a diploid cell while a gamete contains only half the number of chromosomes of its parent cell, and it is called a haploid cell.

3. Identical twins

4. nucleotide triplets

5. A gene is a sequence of nucleotide bases that specifies certain products; RNA or proteins. It is the segment of DNA that holds the information to build and maintain an organism's cell and also pass genetic traits to offspring. Hence, it is the molecular unit of heredity in living organisms.

The DNA is a long double-helical structure that stores the genetic information in our cells. It consists of two long polynucleotide chains composed of the four nucleotides subunits (A, C, G, T).

In order for the long strand of DNA to fit into the cell's nucleus, it is coiled around certain proteins called HISTONES to form Chromatin, which undergoes further coiling and organization to to linear CHROMOSOMES.

The chromosomes are structured within the nucleus, that are made up of the cell's genetic material (DNA). In eukaryotic cells, the nucleus houses the cell's DNA and directs protein synthesis (expression of the information encoded by genes).

"DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA profiles are a match, then the evidence came from that suspect." information from a website so reword it a bit and you should be ok.

In the process of genetic profiling/ data fingerprinting, genetic profiling is a process that can be compared between two people/samples.

DNA profiling compares only the most variable sections of DNA, which has an advantage over whole genome sequencing when seeking to identify genetic changes between two individuals.

In the field of biology known as comparative genomics, genome sequences from various species—including humans, mice, and a broad variety of other organisms—from bacteria to chimpanzees are compared.

"DNA fingerprinting is a lab method used to connect biological evidence to a defendant in a criminal investigation. A DNA sample from a suspect is compared to one acquired from a crime scene. The evidence originated from that suspect if the two DNA profiles match.

Therefore, genetic profiling is compared between two people/samples.

Answer:

D. Can save species from extinction

Explanation:

As saving species from extinction is what Endangered Species Act would want as endangered means that the animal is close to dying and is in danger of being there no longer

Benefits of the Endangered Species Act can prevent the extinction of certain species. So, the correct option is D.

One of America's most important and effective environmental legislation is the Endangered Species Act. It shows that Americans are willing to cooperate in order to preserve and safeguard the species that are most in danger of going extinct for good.

For landowners, government organisations, and concerned citizens, the legislation offers reasonable, well-balanced options for preserving endangered wildlife and its ecosystems. There are three crucial components in it:

1. Preventing harm or extinction of the listed species

2. Creating strategies to reestablish healthy populations

3. Protecting habitat, which is crucial to the survival of these species.

Therefore,  the correct option is D.
