What is oxygen and how would you describe it ?
Answer:
Oxygen is a colourless, odourless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere.

What happens to the actin and myosin during a muscle contraction?
•The actin filaments push against the myosin filaments, making the myosin filaments smaller
•The actin filaments are forced inward by the flexing of the muscle
•The myosin filaments remain in place as they pull the actin filaments inward
•The myosin filaments compress the actin filaments, making the actin filaments smaller
Answer:
C, The myosin filaments remain in lace as they pull the actin filaments inward
Explanation:
Muscles contract when the heads on the myosin filaments latch onto the actin filaments, drawing them inward. As a result, the entire sarcomere shortens, resulting in a muscle contraction.
The myosin filaments remain in place as they pull the actin filaments inward. The correct option is C.
Thus, Actin filaments are drawn inward as a result of the myosin heads cycling and attaching to fresh binding sites, which causes the muscle to contract.
Multiple sarcomeres within muscle fibres engage in this process simultaneously, which causes the entire muscle to contract.
In conclusion, during muscle contraction, actin filaments are actively pulled inward by myosin filaments, specifically the myosin heads, by the sliding filament mechanism. Muscle contraction and movement depend on the coordinated action of myosin and actin filaments.
Thus, The myosin filaments remain in place as they pull the actin filaments inward. The correct option is C.

6. What percentage of the offspring will show the phenotype of the dominant and
recessive allele?
A. 50% will show the phenotype of the dominant allele and 25% will show the
phenotype of the recessive allele.
B. 75% will show the phenotype of the recessive allele and 25% will show the
phenotype of the dominant allele.
C. 75% will show the phenotype of the dominant allele and 25% will show the
phenotype of the recessive allele
D. 100% will show the phenotype of the dominant allele and 0% will show the
phenotype of the recessive allele.
Answer:
C. 75% will show the phenotype of the dominant allele and 25% will show the
phenotype of the recessive allele
Explanation:
on the punnet square you can see that 3/4=75/100 of the individuals have the dominant allele so they will manifest the dominant phenotype the other 25% don't have the dominant allele
75% will show the phenotype of the dominant allele and 25% will show the phenotype of the recessive allele.
What is Punnett square?An illustration of the potential genotypes of an offspring resulting from a specific cross or breeding event is called a Punnett square. Knowing the parents' genetic make-up is necessary to create a Punnett square. They have tabular representations of the different conceivable combinations of their gametes.
The underlying presumption is that different qualities assort independently from one another and that each feature is determined by a single gene locus. There are numerous exceptions, even if this is generally true for many beneficial qualities, particularly when picking characters for plant or animal breeding.
This device was developed in the 20th century, many years after Mendel's groundbreaking genetics experiments.
Therefore, 75% will show the phenotype of the dominant allele and 25% will show the phenotype of the recessive allele.

Which process is responsible for the loss of biomass at each level of the ecosystem
Answer:
The correct answer is - excretion
Explanation:
In any ecosystem, there is a loss of biomass and energy at each level of the energy pyramid or trophic level. Biomass and energy both lost due to completing the life processes.
All the biomass is eaten at each level as not all food they take completely digested and removed by the process of excretion in various forms such as solid feces, carbon dioxide, and water in respiration and water and urea in urine.

During melosis II:
chromosomes line up along the middle plate in double file
genetic variation results from crossing over
two diploid daughter cells are formed
sister chromatids split
four haploid daughter cells are formed
Answer:
chromosomes line up along the middle plate in double file
sister chromatids split
four haploid daughter cells are formed
Explanation:
Crossing over or recombination is the interchange of genetic material between non-sister chromatids. This process (crossing over) occurs during the prophase of meiosis I. Meiosis II is the second meiotic division that involves the separation of sister chromatids. In metaphase II, the centromeres of paired chromatids align on the equatorial plate of each daughter cell to be subsequently separated in anaphase II. At the end of meiosis II, four daughter cells are formed (i.e., four gametes), each with the same haploid number of chromosomes.

What impact could artificially raising the carrying capacity have on the deer
population long term?
Answer:
Deer population increases.
Explanation:
Deer population increases if increasing occur in carrying capacity of an ecosystem by artificial means because more food, water, shelter and other resources are available to the deer due to increasing carrying capacity of an ecosystem. If food, water and shelter are available in large amount to the deer so they reproduce rapidly and increase occur in their population.
