Answer:
b. They cannot reproduce outside of a host cell.
Explanation:
Viruses are parasitic organisms that need a host in order to thrive and reproduce. This means that they cannot replicate outside of a host cell, but can only do this by parasitizing it. They have to find a host cell in order to continue their life-cycle or else they won't thrive. The word "obligate" means being restricted to a specific mode or function in life. This shows that the virus has a restriction when it comes to reproduction. It cannot reproduce without finding a host cell.

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.

Using the Gizmo, find a carbon atom path from the atmosphere to the cement plant. (Hint:
One of the ingredients in cement is limestone.)
Path:
Answer:
Path: Atmosphere -> Ocean -> Shells -> Limestone -> Cement Plant
The path of a carbon atom is - air, ocean, shells/coral reef, limestone, cement plant.
Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron, and other ingredients.
Common components used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace, silica sand, and iron ore.Limestone form the coral reefs that are massive structures deposited by coral polyps.Coral reefs get their carbonate from the ocean that comes from air Carbon in limestone is produced in a cement plant when heated to make calcium oxide. The waste product is carbon dioxide.Thus, the path of a carbon atom is - air, ocean, shells/coral reef, limestone, cement plant.

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.
B. What is the diploid number of the original cell?
(how many chromosomes does it have?)
Answer:
equation is 2n = 46
Explanation:
humans have 2 sets of 23 chromosomes
Two full sets of chromosomes make up a diploid cell. Humans mostly have diploid cells, which have 23 pairs of chromosomes each, for a total of 46 chromosomes.
What are chromosomes?There are 22 pairs of autosomes and two sex chromosomes in this. The person received one copy of each pair of chromosomes from their mother and the other copy from their father.
A "diploid cell" is one that has two copies of each chromosome; human somatic cells are diploid and have 46 chromosomes, 22 pairs of autosomes, and a pair of sex chromosomes.
Histones, which function as packing proteins for the majority of eukaryotic chromosomes, join forces with chaperone proteins to attach to and compress the DNA molecule, maintaining the integrity of the molecule.
Therefore, diploid cells, have 23 pairs of chromosomes each, for a total of 46 chromosomes.

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 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.
