Native to the southeastern us, what is the largest and most venomous snake in north america?
answer :
eastern diamondback rattlesnake.
Native to the southeastern US Rattlesnake, is the largest and most venomous snake in north America.
Rattlesnakes are the largest venomous snakes found in the United States, and numerous species can be found in the country's ecosystems. They can strike one-third of their body length or more quickly and accurately from any position, whether they are coiled or stretched out.
Although they may not always rattle before biting, rattlesnakes may use their rattles as a warning when they feel threatened. They may be seen lying on the ground next to open areas, logs, or boulders. Rattlesnakes inhabit a variety of habitats, including beaches, prairies, mountains, and deserts, where people work. For the treatment of signs of progressive envenomation (such as worsening local tissue injury and systemic symptoms), antivenom is recommended.

When there is a point mutation on initial DNA sequence What are the effects on the final protein?
A point mutation can result in one of three possible effects with respect to protein: (1) a change to a different amino acid, called amissense mutation; (2) a change to a termination codon, called anonsense mutation; or (3) creation of a new sequence that issilent with regard to protein sequence but alters some aspect.
A point mutation is a genetic mutation where a single nucleotide base is changed, inserted or deleted from a DNA or RNA sequence of an organism's genome.
Point mutations have a variety of effects on the downstream protein product—consequences that are moderately predictable based upon the specifics of the mutation.
These consequences can range from no effect (e.g. synonymous mutations) to deleterious effects (e.g. frameshift mutations), with regard to protein production, composition, and function.

With the aid of a diagram state the processes of egg formation.
The Yolk – It starts with the yolk forming in the hen’s ovary. When the yolk reaches the right size, it is released into the oviduct, where the rest of the egg will form.
The White – In its journey through the oviduct, the next layer to be added is the egg white (albumen). This layer takes about 3 hours to be formed.
The Shell Membrane – The next layer to be added in the oviduct is the shell membrane. This takes about 1.25 hours. It is a very thin layer between the egg white and the shell, and it almost looks like tissue paper. Have you ever cracked an egg shell but the egg didn’t break? The shell membrane was still intact holding everything together.
The Shell – The egg then reaches the hen’s uterus, also known as the shell gland. This is where the shell is added to the egg. The shell is also formed in layers over the course of 19 hours, where pigment is also added. All egg shells begin as white. Blue and brown pigments are added during the shell forming process. The color of the pigment depends on the breed of chicken.
An interesting note about egg coloration. Brown pigment is added last in the formation of an egg shell. It is only found on the surface of the egg. When you crack open a brown egg, the inside of the egg shell will be white. Blue pigment is added early in the shell formation process. The color will penetrate the entire shell. When you crack open a blue egg, the inside of the shell will be blue. Green eggs are a combination of brown and blue pigments. White eggs contain no pigment at all.
The Bloom – The bloom is the protective layer or cuticle that covers the egg shell and is the last layer added in egg formation. It is added after the egg leaves the uterus, right before it exits from the hen’s vent. This coating seals out bacteria and maintains the moisture inside the egg. Leaving the bloom intact will help keep your eggs fresher, longer.

Answer:
Explanation:
Egg formation, also known as ovulation, is the process by which a mature female reproductive cell, or ovum, is released from the ovary. This process occurs in the female reproductive system, which is responsible for the production, maturation, and release of eggs as well as the production of hormones that regulate the menstrual cycle.
Here is a diagram illustrating the process of egg formation:
The process begins with the hypothalamus, a region of the brain that produces hormones that stimulate the pituitary gland to release follicle-stimulating hormone (FSH).
FSH travels through the bloodstream and stimulates the ovarian follicles, which are small sacs containing an immature egg.
One of the ovarian follicles begins to mature and secrete estrogen, a hormone that stimulates the growth and development of the female reproductive organs and the development of secondary sexual characteristics.
As the follicle continues to mature, it releases increasing amounts of estrogen, which causes the lining of the uterus (endometrium) to thicken in preparation for pregnancy.
Around the midpoint of the menstrual cycle, the level of estrogen in the body reaches a peak, triggering the release of luteinizing hormone (LH) from the pituitary gland.
LH stimulates the mature follicle to rupture and release the egg, a process called ovulation.
The egg is then swept into the fallopian tube, where it may be fertilized by sperm if sexual intercourse has occurred.
If the egg is not fertilized, it will be expelled from the body during the next menstrual period.

What are the 4 bases of DNA and how do they pair?
The four base pairs in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T) (T). These bases come in particular pairs (A with T, and G with C).
Chargaff's rules are particular patterns for how the bases go together. According to these criteria, adenine and thymine are always paired, while cytosine and guanine are. They bear Edwin Chargaff's name, the researcher who discovered the pattern, as their namesake. According to Chargaff, all DNA molecules typically contain an equal ratio of adenine to thymine and cytosine to guanine. He postulated that if one complimentary base was present, the other side of the DNA helix must include the other, and as a result, he developed the base-pairing principles that are still in use today.

How will you determine the percentage germination of mongo seeds?
The percentage germination of mongo seeds is an important measure in evaluating seed quality. It is also used to determine seedling vigor, which is important for successful seedling establishment and growth.
To determine the percentage germination of mongo seeds, one should first prepare the sample. This involves counting out the desired number of seeds and placing them in a container filled with warm water. The water should be changed and the seeds should be agitated periodically for about 12 hours. After 12 hours, the seeds should be drained and placed in a moist paper towel.
Once the seeds have been placed in the moist paper towel, they should be incubated in a warm location for several days. This allows the seeds to begin the germination process. During the incubation period, the paper towel should be monitored and kept moist.
Once the germination process has begun, the percentage germination can be calculated. To do this, the seeds should be counted and the number of seeds that have germinated should be recorded. The percentage of germination can then be calculated by dividing the number of germinated seeds by the total number of seeds, and multiplying the result by 100.
Another important part of the process is determining the quality of germination.
