A botanist wants to see how different colored light waves influence the growth of pea plants. She puts the same number of seeds into three identical pots with the same kind and amount of soil.she then gives them the same amount of water every three days for the length of the experiment. One pot is placed into a dark windowless closet. Another pot is left on the windowsill,and the third is placed under a lamp with a green bulb.she records the height of each plant every day for three months.


What is the independent variable in this experiment?

Answers

Answer 1

Answer:

The amount of light they receive.

Explanation:

In an experiment, the independent variable is the part of the experiment that the experimenter changes. In this experiment, the only thing that's different for each of the plants is the amount of light they receive. Everything else is the same - the same amount of soil, same amount of water, same pots, and so on.

Answer 2

The independent variable in this experiment is the amount of light received by each plant.

What is an independent variable?The experimenter manipulates or alters the independent variable, which is expected to have a direct effect on the dependent variable.For example, here the amount of light given to each plant is different and will have an effect on the growth of pea plant.In an experiment, the dependent variable is the variable that is being tested and measured, and it is 'depending' on the independent variable. here the growth of pea plant is dependent variable.

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.

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.

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.

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

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.

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.

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.

Why does the cell sometimes have to expend energy to move individual molecules across the cell membrane?

Answers

Answer:

Normally, molecules move naturally down a concentration gradient [From an area of high concentration to an area of low concentration] by a process called diffusion. However, sometimes the concentration of the needed substance is higher in the cell than out of it, so the cell uses a different process called Active Transport. Unlike Diffusion, Active transport requires energy, as it is going against a concentration gradient.

Cells expend energy to move cells across the cell membrane as they use Active transport rather than diffusion.
