which is true about both endocytosis and exocytosis? check all that apply
they use vesicles for cell transport
they require energy for cell transport
they remove wastes from the cell
they move small, fat-soluble substances
Answers
Answer: they use vesicles for cell transport and they require energy for cell transport
Explanation:
Both endocytosis and exocytosis use vesicles for cell transport, require energy for cell transport. The correct options are a and b.
What is endocytosis and exocytosis?Endocytosis is the transport of material into the cell, while exocytosis is the transport of material out of the cell.
The distinction can be seen because a vesicle forms around the molecule entering endocytosis. Exocytosis is basically the inverse of endocytosis.
Endocytosis and exocytosis both require energy in the form of adenosine triphosphate (ATP), which is used in the movement of substances into and out of the cell.
Endocytosis is classified into three types: phagocytosis, pinocytosis, and receptor-mediated endocytosis.
Exocytosis is the process by which vesicles fuse with the plasma membrane and release their contents outside of the cell. Exocytosis and endocytosis are both active transport processes.
Thus, the correct options are a and b.

Characteristics of evolution in points.
Answers
Answer:
Five different forces have influenced human evolution: natural selection, random
genetic drift, mutation, population mating structure, and culture. All evolutionary biologists
agree on the first three of these forces, although there have been disputes at times about the
relative importance of each force. The fourth and fifth forces are new in the sense that they
are not explicated in more traditional texts. This is not an attempt to develop a “new”
theory of human evolution. Instead, the forces of population mating structure and culture
are arbitrary categorizations used to organize several different phenomena of human
evolution. Scientists agree on the phenomena themselves, although they do not always
organize them the same way.

Step 1: Add approximately 25 mL of water to a 50-mL graduated cylinder.
Step 2: Measure and record the initial volume of the water to the nearest 0.1 mL.
Step 3: Carefully slide the object into the graduated cylinder. Measure and record the final volume of the water to the nearest 0.1 mL.
Step 4: Determine the volume of the object by subtracting the measurements in steps 2 and 3.
What pattern in these data could be used to predict the final volume if the initial volume is known?
The final volume is the sum of the initial volume and the volume of the object.
The initial volume is the sum of the final volume and the volume of the object.
The volume of the object is the sum of the initial volume and the final volume.
The final volume is the difference between the initial volume and the object’s volume.
Answers
Answer:
The final volume is the sum of the initial volume and the volume of the object.
Explanation:
Since we know that the volume of the object is the difference between the final and the initial volume, let the volume of the object be ∆V, let the initial volume be V1 and let the final volume be V2.
From;
∆V= V2 - V1
V2= ∆V + V1

Explanation:
As stated in this question, Semi-conservative model of DNA replication is the acceptable model of replication in which the two synthesized molecules of DNA consists of one new and one old strand each. DNA replication is carried out by an enzyme called DNA polymerase.
In the semi-conservative model, a double stranded DNA separates into two single strands. Each single strand is used as a template for DNA polymerase to synthesize nucleotides based on complementary base pairing i.e. For every Adenine base, Thymine is added and for every Guanine, Cytosine is added and vice versa.
In this question showing an image of a DNA molecule undergoing replication using semiconservative model, the first DNA molecule consists of the following nucleotides on the old strand and its synthesized nucleotides on the new strand:
Old strand - New strand
1. T - A
2. G - C
3. A - T
4. C - G
5. C - G
6. C - G
On the second DNA molecule, we have the following nucleotides on the old strand and its synthesized nucleotides on the new strand.
Old strand - New strand
7. A - T
8. C - G
9. T - A
10. G - C

In rigor mortis, muscle tissue becomes locked in position because myosin heads are tightly attached to neighboring actin thin filaments. This lock-up is prevented in living muscle because ordinarily myosin is rapidly displaced from the thin filament by:_________.A. binding of a new molecule of ATP B. hydrolysis of ATP C. release of ADP after ATP hydrolysis D. release of phosphate after ATP hyrdolysis
Answers
Answer:
The correct answer is option A. binding of a new molecule of ATP.
Explanation:
Actin and myosin are complementary filaments present in muscle, actin is thin and myosin is a thick filament, these two filaments are responsible for the movement by muscle contraction and relaxation. Actin and myosin head shows great affinity towards one another.
Myosin heads are tightly attached to neighboring actin thin filaments due to its affinity to actin, however, myosin at other pockets also show a huge affinity for ATP. If myosin is bound to actin the affinity for ATP is changed and if new ATP bounds to the empty pockets it changes the conformation of myosin and prevents lockup or binding of the actin-myosin protein.

b. reproduction
c. mitosis
Answers
Answer:
A. Chromosomes
Explanation:
A Chromosome is some thing carrying genetic information in the form of genes.
We find DNA on the chromosomes, in every living cell that an organism owns. So, the correct option is A.
What is Chromosome?The word chromosome comes from the Greek words for color (chroma) and body (soma). Chromosomes are so named because they are cell structures, or bodies, that are strongly stained by certain color dyes used in research.
Chromosomes are defined as structures found inside the nucleus of a cell that are organized into genes from proteins and DNA. Each cell normally has 23 pairs of chromosomes.
These are threadlike structures which are made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell.
Therefore, the correct option is A.

The generation of a knock-out organism generally requires all the following EXCEPT ________. The generation of a knock-out organism generally requires all the following EXCEPT ________. knowledge of the sequence product embryonic stem cells knowledge of the target sequence a targeting vector
Answers
Answer:
knowledge of the sequence product
Explanation:
A gene knockout is a technique used in molecular genetics to deactivate target genes in an organism in order to study their functions by reverse genetics (i.e., gene loss). Knockouts are generated by different methods including, for example, homologous recombination or site-specific nucleases (zinc-fingers, TALENS, CRISPR/Cas9). These techniques require to know a priori the sequence of each gene to be knocked out in order to target desired mutations. In the last years, the CRISPR/Cas9 tool has gained attention to knockout genes of interest because it is a genome editing system that can be easily used for deletion or insertion of bases.
You want to know if black squirrels or brown squirrels have a greater birth rate. Your ALTERNATIVE hypothesis is:_________.
Answers
Answer:
Natural selection is a mechanism of evolution proposed by Charles Darwin. It is the differential survival and reproduction of individual due to the difference in the phenotype. Over time, this process results in populations which are better adapted to their environment as they tend to survive and produce new offspring. The brown squirrels with thick coat survive at a higher rate than the brown sqirrels without the thick coat. Thick coat is a adaptation for survival in cold winters which are chosen over the other and allowed to reproduce.

Based on your knowledge of reproduction in bryophytes and ferns, is the presence of flagellated sperm in cycads surprising? Why or why not?
Answers
Answer:
The correct answer is - All plants share a similar life cycle
Explanation:
The sperms that the bryophytes are biflagellated whereas in ferns these are multi-flagellated that helps in the swimming to the archegonia or female part to perform the fertilization, due to the presence of water.
The sperms in cycads also have flagella for the same purpose of swimming in the pollen tube. The ferns and the bryophytes both require the same or similar life cycle that includes the flagella and water for the formation of the zygote.
Two genes interact to produce various phenotypic ratios among F2 progeny of a dihybrid cross. Design a different pathway explaining each of the F2 ratios below, using hypothetical genes R and T and assuming that the dominant allele at each locus catalyzes a different reaction or performs an action leading to pigment production. The recessive allele at each locus is null (loss-of-function). Begin each pathway with a colorless precursor that produces a white or albino phenotype if it is unmodified. The ratios are for F2 progeny produced by crossing wild-type F1 organisms with the genotype RrTt. Which statement is correct? 12/16 white: 3/16 green: 1/16 yellowA) At least one copy of both dominant alleles results in white; at least one copy of one of the dominant alleles also results in white, but at least one copy of the other dominant allele produces green; and the absence of either dominant allele produces yellow.B) If both dominant alleles are present, the result is green. At least one copy of one specific dominant allele is required for yellow. If that dominant allele is not present, the result is white, regardless of whether the other dominant allele is present.C) At least one copy of each dominant allele results in white, at least one copy of either dominant allele produces green, and the absence of either dominant allele produces yellow.

Answers
Answer:
Please find the flowchart attached as an image
Explanation:
DNA is the genetic material contained in the cells of living organisms. The DNA contains a segment called GENE, which contains information used to produce useful products needed in the cell. The information contained in the gene is expressed to produce PROTEINS.
PROTEINS are responsible for many metabolic activities that occurs in a cell. The CELL functions due to activities of the proteins produced by gene expression. When similar cells come together, they form TISSUES. An aggregation of tissues performing similar functions form ORGAN. Organs functioning similarly come together to form ORGAN SYSTEM. A collection of organ systems in the body forms the ORGANISM.
