Select the correct answer from the drop-down menu. What are the two specific concerns of species diversity? Species diversity is concerned with both A, species survival
B, species richness
C, species growth rate
D, species demographic and A, evenness of species abundance
B, species survival
C, species growth rate
D, species gender
Answer:
The answer above was wrong. Maybe it wanted it put in a different way but don’t do what i did
Explanation:
Plato
The two specific concerns of species diversity are species survival and evenness of species abundance. The correct options are A and B.
What is species diversity?"Species diversity is defined as the number of different species present in an ecosystem and their relative abundance." When all of the species present are equally abundant in the area, diversity is greatest.
Species diversity is a measure of the number of different species found in a given ecosystem or habitat.
It is critical to be concerned about species survival because the extinction of a species can have a negative impact on the entire ecosystem.
Furthermore, the evenness of species abundance is important to consider because the dominance of one or a few species can have a negative impact on the diversity and stability of an ecosystem.
Thus, the correct options are A and B.

The Paleozoic Era began approximately 550 million years ago and ended approximately 252 million years ago.
What is Paleozoic Era?The Paleozoic Era is a geological epoch that lasted about 541 million years and ended about 252 million years ago.
It is also known as the "Age of Invertebrates" because it witnessed the rise and dominance of numerous invertebrate groups, including trilobites, brachiopods, and ammonites.
From oldest to youngest, the Paleozoic Era is divided into six periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian.
Many significant events in the evolution of life on Earth occurred during this time period, including the Cambrian period's explosion of diversity, plant and animal colonization of land, and the emergence of reptiles and insects.
Thus, the answer is 550 million years ago.

Do catfish have hair?
a. yes
b. no
Answer:
no they do not have hair, even tough it may look like they have hair its only pieces of skin.
Explanation:
Catfish do not have hair. They have barbels, which are long, thin feelers that are used to sense their surroundings. Hence option B is correct.
The barbels are covered in taste buds, which allow the catfish to taste the water and find food. Hair is made of keratin, which is a protein. Catfish do not have keratin in their skin, so they cannot grow hair.
However, some catfish species have barbels that are covered in small, hair-like projections. These projections are not actually hair, but they are similar in appearance.
Therefore, option B) No is correct.

How is it possible for a mutation not to produce any visible effect in an
organism?
Answer:
Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.
Which molecules do cells need to release energy? (Can you make it look like 7th grade writing please well if you can)
Answer:
Cells need oxygen and glucose.
Without oxygen, electron transport chain cannot take place and the cells cannot get the energy they need (since the cell uses oxygen to break down glucose which os what produces energy). When the cells cannot perform their function, they die.
Explain how a carbon atom from a CO2 molecule in the air can end up as a carbon atom in a protein in a plant cell
Answer:
Photosynthesis and metabolism are among the most complex areas in biology so given the nature of this forum I've kept the answers simple and brief.
Carbon is of central importance to all biological systems due to its special bonding properties allowing it to form various bonds with other atoms and produce a wonderfully complex range of molecules used by life.
In photosynthesis inorganic carbon in carbon dioxide gas is fixed to hydrogen to produce sugar, an organic molecule. In this case the carbon gains electrons so it is 'reduced' and this process requires energy in the form of light. Once in sugar form, the process can be reversed and the carbon can be oxidised back into carbon dioxide during cellular respiration, releasing energy.
So in photosynthesis, the carbon from carbon dioxide is reduced to form a sugar molecule. When transitioning to respiration, the carbon in the sugar is oxidised to form carbon dioxide again in the reverse reaction to photosynthesis.
The carbon is transferred between molecules through various intermediate steps during these processes, involving enzymes (biological catalysts) to assist in cleaving specific bonds at each stage. During cellular respiration (an energy release reaction) as the carbon is successively oxidised electrons are liberated that are used as part of the energy release. These electrons are captured or 'carried' by special organic molecules called NAD and FAD (reducing them) which in turn can then be oxidised to produce the universal energy currency of life: ATP molecules. ATP is a small bio molecule containing a high energy phosphorous bond that can be broken to release energy to do cellular work. It is used by all life that we know of and is the ultimate product of cellular respiration.
The carbon atom in a CO₂ molecule in the air can become a part of the
cellulose molecule in a plant by the carbon dioxide molecule reacting with the water during photosynthesis to form Glucose.
This formula can use for the reaction: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
The glucose molecule formed is then translocated to other parts of the
plants which are such as the roots and stems and help in the formation of cellulose.
Also, aThis is basically how the carbon atom in carbon dioxide becomes a cellulose molecule.Learn more about:

this adaptation is beneficial in
their ability to become resistant
to antibiotics
Answer:
Antibiotics, also known as antimicrobial drugs, are drugs that fight infections caused by bacteria. Alexander Fleming discovered the first antibiotic, penicillin, in 1927. After the first use of antibiotics in the 1940s, they transformed medical care and dramatically reduced illness and death from infectious diseases.
The term "antibiotic" originally referred to a natural compound produced by a fungus or another microorganism that kills bacteria which cause disease in humans or animals. Some antibiotics may be synthetic compounds (not produced by microorganisms) that can also kill or inhibit the growth of microbes. Technically, the term "antimicrobial agent" refers to both natural and synthetic compounds; however, many people use the word "antibiotic" to refer to both. Although antibiotics have many beneficial effects, their use has contributed to the problem of antibiotic resistance.
Antibiotic resistance is the ability of bacteria or other microbes to resist the effects of an antibiotic. Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm.

Explain the process of evolution through isolation
that results in speciation.
Answer:
Speciation is the process of formation of a new genetically independent group of organisms, called species, through the course of evolution. The process of splitting of genetically homogenous population into two or more populations that undergo genetic differentiation and eventual reproductive isolation is called speciation.
Answer:
Explanation:
Evolution is a natural phenomenon by which inheritable characteristics of a species change over generations. It mainly relies on processes such as natural selection, genetic drift, migration, and mutation. ... Isolation (geographical or reproductive) prevent the flow of genetic material between the populations.

DNA Replication
Explanation:
In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. DNA replication occurs in all living organisms acting as the most essential part for biological inheritance. Additionally, Walther Flemming's drawing of chromosomes. This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. The outcome of binary fission is two new cells that are identical to the original cell.
