Answer: Elephants have few offsprings, so they need to protect them from predators.
Explanation:
Herd behaviour is a behaviour which is collectively shown by organisms in the group. The organisms move, feed and fight the predator in groups. This is a kind of social behavior shown even by the animals.
Elephants also show this kind of social behavior. They move in herd (flock). The tall and older members move at the edges when the elephants moce in herd. This is to protect the young once in the middle from the attack of predators as the young once are incapable of protecting themselves from predators. Also the elephant mother gives birth to only one offspring at a time. Thus the population may suffer if the offspring is not protected.

A key is a sorting device that lists choices between certain observed characteristics. A dichotomous key is the simplest means of identification. The word dichotomy means "cut or split into two parts." Hence, a dichotomous key is a two-part or two-choice key. It asks whether a particular organism has one trait or another—either yellow or brown, either large or small, etc. For this project, you will classify different pieces of fruit by responding to dichotomous questions. In the fruit lab below, respond to the questions to help the computer identify all the pieces of fruit. After conducting the fruit lab, answer the following questions: What was your identification accuracy? Identify at least three types of characteristics that you were asked about as you helped the computer identify a fruit. How is the fruit lab like a dichotomous key?

Why is the largest dna fragment band found closest to the well in which it was placed?
In agarose gel electrophoresis, larger DNA fragments migrate less due to the molecular sieve effect of the gel matrix which impedes their movement. Thus, they are found closer to the well they were loaded into, while smaller fragments move farther away.
Explanation:The largest DNA fragment band is found closest to the well in because it travels slower through the gel during agarose gel electrophoresis. During this process, DNA fragments are loaded into a gel and an electric field is applied. Due to its negative charge, DNA moves towards the positive electrode. However, the gel matrix forms a molecular sieve, impeding the movement of larger molecules, allowing smaller fragments to pass through more readily. Hence, larger DNA fragments migrate less, staying closer to the well from which they were loaded, while smaller fragments travel farther.

A skeletal muscle deprived of adequate atp supplies will _____. a skeletal muscle deprived of adequate atp supplies will _____. sequester all free calcium ions into the sarcoplasmic reticulum immediately relax enter a state where actin and myosin are unable to separate fire many more action potentials than usual and enter a state of "rigor"
A skeletal muscle deprived of adequate ATP supplies will enter a state of rigor mortis.
When a skeletal muscle is deprived of adequate ATP supplies, it enters a state known as "rigor mortis." Rigor mortis is a natural post-mortem phenomenon that occurs in the muscles of a deceased organism, typically a human body.
Here's how it happens: ATP is essential for muscle contraction and relaxation. During life, ATP is constantly produced and used to power the cross-bridge cycling between the protein filaments actin and myosin in muscle cells. This cycling allows muscles to contract and relax as needed for various movements.
However, when an organism dies, ATP production ceases, and the available ATP is depleted. Without ATP, the myosin heads that are firmly attached to actin cannot detach from it. As a result, the muscle becomes rigid and locked in a contracted state. This rigidity is what we observe as rigor mortis.
The onset of rigor mortis typically occurs a few hours after death, peaks around 12-24 hours after death, and then gradually dissipates as the muscle proteins break down due to enzymatic processes and decomposition. It's important to note that rigor mortis is a temporary condition and does not last indefinitely. The exact timing and duration of rigor mortis can vary depending on factors like temperature, pH levels, and the individual's overall health at the time of death.

If a skeletal muscle lacks adequate ATP, it enters a state of rigor where the muscle remains contracted because the actin and myosin proteins cannot separate. The muscle does not immediately relax, sequester all free calcium ions, or fire many more action potentials.
Explanation:A skeletal muscle deprived of adequate ATP (adenosine triphosphate) supplies will enter a state known as rigor. This is because ATP is essential for muscle contraction and relaxation. Without enough ATP, the actin and myosin proteins within the skeletal muscle fibers cannot detach from each other, causing the muscle to remain in a contracted state, or rigor. Therefore, the muscle does not relax immediately or sequester all free calcium ions into the sarcoplasmic reticulum, and it does not fire many more action potentials than usual. Skeletal muscles need ATP to function correctly and carry out processes like muscle contraction and relaxation.

Why is it more practical to prepare karyotypes by looking at somatic diploid cells rather than haploid gametes?
The haploid gametes only contain half of the chromosomes. That is why it is more practical to prepare karyotypes by looking at somatic diploid cells rather than haploid cells.
What is karyotyping?
It is a test for examining the chromosomes in a given sample of cells. This test is used for identifying the genetic problems that have resulted in a disorder or disease. Almost any tissue can be used for performing this test. These can include Amniotic fluid, Blood, Bone marrow, or even placenta.
The test is performed by placing the sample in a special dish or a tube. It is then allowed to grow in the laboratory. Then the cells are later taken from the new sample and are then stained.
A microscope is then used for to examine the size, shape, and number of chromosomes in the sample of cells. The sample that is stained is photographed for showing the arrangement of the chromosomes. This arrangement is called a karyotype.
This can be used for identifying certain problems through the number of chromosomes or the arrangement of the chromosomes. Thousands of genes are stored in DNA and the basic genetic material is present in the chromosome.
Therefore, the haploid gametes only contain half of the chromosomes. That is why it is more practical to prepare karyotypes by looking at somatic diploid cells rather than haploid cells.

Antimicrobial agents that damage the viral envelope __________.
Antimicrobial agents that damage the viral envelope effectively inhibit viral growth without harming the host by disrupting the virus's ability to attach to and enter host cells.
Explanation:Antimicrobial agents that damage the viral envelope are effective in inhibiting viral growth without damaging the host. These agents interfere with the integrity of the viral envelope, which is composed of lipids and proteins. By disrupting the envelope, the agents prevent the virus from attaching to and entering host cells, thereby inhibiting viral replication. One example of an antimicrobial agent that damages the viral envelope is Tamiflu, which inhibits the viral enzyme neuraminidase found in the influenza viral envelope.

Which cranial nerve is responsible for transmitting visual information?
The optic nerve is the cranial nerve responsible for transmitting visual information from the eye to the brain. It is one of the 12 cranial nerves in the human body which each have unique functions. Some cranial nerves transmit sensory information, others transmit motor information, and some a combination of both.
Explanation:The cranial nerve responsible for transmitting visual information is the optic nerve. This nerve function includes transmitting visual signals from the eye over the axons of retinal ganglion cells, which form the optic nerve, to the brain. Specialized cells within this nerve carry various types of information such as form, movement, depth, brightness, color, and fine detail.
Humans have a total of 12 cranial nerves, each providing unique functions. For example, the olfactory nerve is responsible for transmitting information about smells from the nose to the brainstem, and the oculomotor nerve controls the opening and closing of the eyelid and some eye movements. However, when it comes to the transmission of visual information, the optic nerve is the primary player.
Generally, some cranial nerves transmit only sensory information, others mainly motor information, and some contain a mix of sensory and motor fibers, catering to the complex needs of our biological system.
