I will like to argue in favor of medical follow-up being mandatory for adults diagnosed with concussions.

A concussion is a traumatic brain injury that affects your brain function which may be as a result of a blow to the head etc.

The brain is regarded as the center of the nervous system and is a very important and delicate organ. During concussions, the brain function gets reduced which should be checked to avoid damage to other cells.

This can be done by medical follow-up to ensure there is no internal bleeding or damage to brain cells and if there is to start immediate treatment for the survival of the patient.

Answer:

True, Pacific salmon spend part of their life in oceans and part in freshwater rivers.

Explanation:

Five species of Pacific salmon thrive in the North Pacific waters of the US and Canada: chinook (also called king), coho, pink, sockeye, and chum salmon. They begin their lives in freshwater streams, lakes, and rivers and migrate to the sea as small fish called smolts.

The branching roots of the mangrove trees slow down the flow of water and help in depositing the sediments which prevent coastal erosions.

Mangroves are halophiles and can grow in saline habitats. They grow worldwide and occur in tropical, and subtropical regions, and are also found in some temperate coastal areas. Mangroves have a complex root system and they are adapted to low oxygen conditions.

The mangroves in Sunderbans are the largest ecosystem in the world. It is the habitat of the largest predator in Asia, the tiger. The name Sunderban comes from Sundari, Heritiera fomies, the mangrove trees which are in abundance in that area.

Mangrove roots harbor microbial species that play important ecological functions in the ecosystem.

INCORRECT: populations increase in a region with conflict.

People immigrate to other areas for job opportunities.

People emigrate to escape persecution due to their ethnicity.

Explanation:

People migrate for better job opportunities, to escape prosecution and high population. Therefore, the false statement is option "C".

The moment of people, animals, and birds to different places from their birthplace is known as migration. Migration can be permanent, temporary, and also can be seasonal in the case of animals and birds. Migration is of four types such as interstate, intercity, inter-country, and intercontinental.

An example of migration is when salmon start life in rivers after that migrate to the sea for food availability and growth. After living in the ocean, they migrate back to the rivers, so that they can produce spawn. Migratory birds such as crows and bluebirds move to a different places in different seasons.

Protein molecules serve as transporters of molecules across the cell membrane.

Movement of molecules against their concentration gradients is a form of active transport.

Proteins are organic molecules which are made from amino acids linked together by peptide bonds.

Proteins embedded in the cell membranes serve as transport molecules as well as receptors.

Based on concentration gradients, proteins can function in passive or active transport.

invasive species - which fights for itself survival and can cause harm to

ecosystem. non-native to an ecosystem

These predators would belong to keystone species. The correct option is B.

Thus, Predators at the highest levels are frequently regarded as keystone species in an ecosystem. Compared to their biomass or abundance, keystone species have a disproportionately strong influence on the composition and operation of their ecosystem.

They are essential in maintaining the ecosystem's balance and preventing the overpopulation of particular species by controlling the populations of other species there.

The dynamics and biodiversity of the ecosystem can be significantly impacted by the removal of a keystone species.

Thus, These predators would belong to keystone species. The correct option is B.

A sharp image is formed when light reflects from a smooth surface.

A reflective image is formed when light bounces off a reflective surface.

Reflective images can be sharp or blurred depending on the surface on which the light rays bounce from.

When the surface is rough, blurred images are formed. On the other hand, sharp images are formed from smooth surfaces. Sharp images are formed by mirrors because they have smooth surfaces.

Biofilms are resistant to antimicrobial chemicals due to genetic diversity.

Biofilms are considered as a reservoir of genetic diversity. The emergence and spread of antibiotic resistance genes increase in biofilm due to horizontal gene transfer (HGT).

HGT can happen through the transfer of plasmids among microorganism cells in a biofilm through conjugation so that's why the antimicrobial resistance is higher in a biofilm than in free-floating bacterial cells.

Mutation in one exon: 1 amino acid will be replaced by another one; variable consequences depending on the amino acid: most of the time a silent mutation; but the Sickle-cell anemia is due to a mutation at the 6th codon of the β gene (Glu->Val).

Explanation:

i googeld it

Codon in the sickle cell DNA is altered by a single nucleotide substitution that is from GAA to GUA that is in option 2, which is a change from the nucleotide adenine (A) to uracil (U) and this takes place  in the beta-globin gene. option 2 is correct answer.

The codon for glutamic acid is GAA is present in normal hemoglobin and changes to GUA in the sickle cell variant due to the A to U substitution at the nucleotide of the codon, and this single nucleotide substitution in the beta-globin gene leads to a change in the amino acid sequence of the protein and a change in the cell structure . This can lead to a variety of health problems, such as anemia and pain and other kidney related diseases.

Hence, a codon in the sickle cell DNA is altered by a single nucleotide substitution that is in option 2 , which is a change from the nucleotide adenine (A) to uracil (U) in the beta-globin gene, so here option 2 is correct answer.
