Reproduction is important for every type of living thing. Without it, species would die out. To ensure their survival, animals have developed unique adaptations to improve their chances of reproducing. Behavioral adaptations are behaviors an organism performs to help it survive. Structural adaptations are physical features that help an organism survive.
The image below shows two peacocks. The male peacock is large and brightly colored. The female peacock is not as colorful. The size and color of the male's feathers attract females. This is an example of a structural adaptation intended to help with reproduction. Another structural adaptation is when male deer grow large antlers to attract females. Animals also use behavioral adaptations to attract mates. For example, male frogs sing to attract females and male spiders dance to attract females.
Plants also have adaptations to help with reproduction. While animals use behavioral and structural adaptations to improve reproduction, plants only use structural adaptations. For example, brightly colored flowers attract butterflies. Certain flowers also have nectar or give off an odor to attract insects. Attracting butterflies and other insects is important because they play a role in reproduction by pollination.
Which of the following describes an adaptation that relates to reproduction?
A. Hawks have sharp beak to help them quickly catch their prey
B. Elks attach leaves and grasses to their antlers to help them appear larger
C. Polar bears have white fur to help them blend into their surrounding environment
D. Whales have a thick layer of fat called blubber
Answers
Answer:
B. Elks attach leaves and grasses to their antlers to help them appear larger
Explanation:
The above option is the correct answer.
As elks appear larger, it tend to make other male elks to be scared to fight that particular elk for a female elk. Also, the female elk becomes more attracted to larger male elk.
Male elk are known to actually retain their antlers for more than half the year. Such elks do not likely group themselves with other males when they have antlers.

Which statement describes Mendel’s hypotheses regarding gametes?
A) gamete carries two genes for a trait.
B) gamete carries one allele for a gene.
C) gamete can carry multiple alleles for a trait.
D) Some gametes are dominant and some are recessive.
Answers
Answer:
The correct answer is B. A gamete carries one allele for a gene.
Explanation:
Gamete (also called sex cell or reproductive cell) is a haploid cell (having half number of chromosome as compared to the parent cell) that is produced through a cell division, termed as meiosis in sexually reproducing organisms.
According to the Law of segregation given by Gregor Mendel-
During the process of gamete formation, the two alleles of each gene segregate from one another so that a gamete carries one allele for a gene.
Thus, option B) is the right answer.

Nicholas,, a 3 year-old boy, is brought into your gastroenterology practice by his mother. They were referred to you by their pediatrician because Ali has been complaining of severe abdominal pain, especially after eating, for the past few weeks. He has an otherwise normal health history. His pediatrician ordered a fecal occult (hidden) blood test, hematocrit, and urinalysis. The fecal occult blood test is positive and the hematocrit (red blood cell count) is lower than normal for a child his age. Body temperature and urinalysis are normal.
You perform a surface abdominal exam, which appears normal, but Ali complains of pain in the lower right abdominal quadrant during palpitation. You order a CT enterography procedure, which uses a contrast dye to make an X-ray of the small intestine. The CT shows a diverticulum. After confirmation with a technetium scan, you diagnose Nicholas withMeckel’s diverticulum.
Answers
Treatment for Meckel’s diverticulum includes surgical removal of the diverticulum.
What do you mean by diverticulum?
Diverticulum is a small pouch or sac that forms in the wall of the digestive tract. It can occur in any part of the digestive tract, including the esophagus, stomach, small intestine, and large intestine. Diverticula can cause symptoms such as abdominal pain, constipation, and diarrhea.
You recommend that Nicholas have a laparoscopic removal of the diverticulum, a minimally invasive procedure that involves making small incisions in the abdomen and inserting a camera and surgical tools to remove the diverticulum. You explain to Nicholas’ mother the benefits of the procedure and the potential risks associated with it.
After the procedure, you recommend that Nicholas follow up with his pediatrician in two weeks. You also suggest that Nicholas and his mother modify his diet to include more fiber and fluids to help ease his symptoms and prevent the diverticulum from returning. You also suggest that Nicholas take an antacid to help reduce the abdominal pain.

Answers
Answer:
chromosomes
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
The complex structures of deoxyribonucleic acid (DNA) and protein found in the cell nucleus are generally referred to as chromosomes.
In sexual reproduction, the chromosomes from parents are found in the cell nucleus and are comprised of deoxyribonucleic acid (DNA), histone proteins, etc. Thus, they are used to store genetic informations in living organisms.
Basically, the human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.
On the other hand, sex chromosomes (X and Y) are responsible for determining the gender or sex of living organisms such as humans.

Examine the mechanism of carbonic anhydrase. If the Zn2 were removed from the active site, and replaced with either Cu , Cd2 , or Fe3 would you expect the enzyme to still be functional
Answers
Answer: No
Explanation:
Carbonic anhydrase (CA; carbonate hydro-lyase) is a zinc-containing enzyme that catalyzes the reversible hydration of carbon dioxide: CO2+ H2O<-->HCO3(-)+H+. The enzyme is the target for drugs, such as acetazolamide, methazolamide, and dichlorphenamide, for the treatment of glaucoma.
The zinc ion is located in a cone-shaped cavity and coordinated to three histidyl residues and a solvent molecule. Inhibitors bind at or near the metal center guided by a hydrogen-bonded system comprising Glu-106 and Thr-199. The catalytic mechanism of CA II has been studied in particular detail. It involves an attack of zinc-bound OH- on a CO2 molecule loosely bound in a hydrophobic pocket. The resulting zinc-coordinated HCO3- ion is displaced from the metal ion by H2O. The rate-limiting step is an intramolecular proton transfer from the zinc-bound water molecule to His-64, which serves as a proton shuttle between the metal center and buffer molecules in the reaction medium.

What is transaction between school and post school destination
Answers
Answer:
The transition between school to a post school is a difficult phase in one's life because it opens a lot of adjustments whether it is socially, mentally and/or psychologically. Most students find it difficult to transfer because of these following reasons visit these links and see the answers below: brainly.ph/question/2641856, brainly.ph/question/2635171, brainly.ph/question/2627976
There are a bunch of strangers. Not all students are gifted with an extropersonal skills that allows them to make friends easily. Transition makes it difficult for introvert pupils to accept.
The new school is bigger than their previous school. Though in others the size of a place is not bothering their performance, there are individuals who find it difficult to adjust when it comes to the size of their environment. For example a student who studied in a small private school with only one section will find it difficult to adjust moving around a larger environment.
There are different teaching styles coming from the school's faculty. Learning styles are somewhat define by the teacher's teaching styles and strategies. In their previous school, some of the seniors might have already leaked the strategies used by the teacher in their school. But in a post school, some students are 100% newbie wherein they have no idea what is going on inside a class of a single professor or instructor. This is difficult since they do have to observe every single day and learn a new way to follow the lesson's phase.
Friends are not with the same post school. It is said that you can go through anything with your friends but most of the time you will never be with them when you transfer to a post school but still you need to move forward and learn to mix with the public.
Lessons are difficult and new. Most learners are not accustomed in learning quick in a new environment especially when the lesson is more difficult and new.
New policies are too intimidating to break. Some students are struggling when it comes to adjusting to rules whether it is inside the classroom or just a simple campus rule so they feel intimidated and and fearful in breaking one. But it must be remembered that rules keep the society moving forward peacefully.
Explanation:
There are different reason for an individual to fear and feel difficulty adjusting to a post school. But one must remember that humans are created with an adaptability skill that allows us to mix well with a new habitat and environment. Social skills are just part of our adaptability. You can just follow the wind and let the flow take you. Life is a constant change and all you have to do is to embrace it to make yourself belong anywhere you go.
