what was the dependent variable
Answer:
Dependent and independent variables are variables in mathematical modeling, statistical modeling and experimental sciences. Dependent variables receive this name because, in an experiment, their values are studied under the supposition or demand that they depend, by some law or rule, on the values of other variables.

What are the properties of a compound ?A compound composed up of two or more elements which are chemically combined with a fixed proportion by their mass.
For example, Water, Sodium Chloride, Ammonium Chloride etc.
They have fixed melting and boiling points.
Formation of compound is a change in chemical reaction and the components of compound are mixed in a fixed proportion.
Two major types of compounds are covalent and ionic compounds.
Covalent compounds refers to formation of covalent bond among two nonmetals, like water or methane. These molecules are neutral and weak.
When metal react with non metal it form Ionic compounds, are held together by opposite charges, so the bond is stronger than covalent compound.

Researchers note that a plant closes its stomata on a hot, dry, windy day. What statement describes the plant response to these
conditions?
A)
The stomatal closings and the environmental conditions are unrelated for this plant.
B)
The stomatal closings and the environmental conditions are unrelated for
this plant.
Water loss and water stress is highest on hot, dry, windy days, so the plant
closes stomata to conserve water.
Hot, dry, windy days are not conducive to pollen spread, so the plant closes
its stomata to prevent pollination.
Photosynthesis is decreased on hot, dry, windy days, so the plant closes its
stomata to prevent carbon dioxide diffusion.
a
D)
Answer:
It is B
Explanation:
i just took it
If a plant closes its stomata on a hot, dry, and windy day, the plant response to these conditions is water loss and water stress is highest on hot, dry, windy days. So, the plant closes its stomata to conserve water.
What do you mean by Stomata?Stomata are the tiny pores present on the surface of the leaves. A huge amount of gaseous exchange may take place in the leaves through these pores for the purpose of photosynthesis.
During photosynthesis, these stomatal pores take carbon dioxide and water is gradually lost, in order to prevent this water loss in hot and humid conditions, the plant closes its stomata.
Therefore, if a plant closes its stomata on a hot, dry, and windy day, the plant response to these conditions is water loss and water stress is highest on hot, dry, windy days. So, the plant closes its stomata to conserve water.

Mutations in which of the following cells would get passed on to the next generation?
I. sperm
II. Skin cell
III. Egg
IV. Neuron
A. II, III, and IV
B. III only
C.I and III
D. I, III, and IV
Answer:
C. I and III
Explanation:
A mutation needs to occur in a gamete cell in order to be passed down to the next generation.
If it occurs in a somatic (body) cell, the mutation will only be present in that organism.
On the other hand, in a gamete cell, the mutation will pass down because gamete cells are directly involved in the genetic makeup of the offspring.
So, since sperm and egg cells are gametes, mutations in those cells would get passed on.
The correct answer is C. I and III

What are the features of Nuclear Receptor Screening Services?
Nuclear receptors (NRs) are a class of proteins responsible for thyroid hormones and sensing steroid and certain other molecules. There are 48 genes in the human genome that code for the NRs. As the largest family of eukaryotic transcription factors, NRs control numerous processes involved in development, cell cycle, and important metabolic pathways.
https://dda.creative-bioarray.com/nuclear-receptor-screening.html
Answer:
The nuclear receptor superfamily comprises a large group of transcription factors that play a key regulatory role in development and homeostasis of multicellular organisms. A special feature of nuclear receptors is their ability to bind to condensed chromatin templates, which makes them important initiators of gene transcription. Moreover, the ability of nuclear receptors to sequentially recruit a variety of transcription factors and coregulators to target promoters and to orchestrate the whole process of gene transcription confirms their biological significance and stimulates intensive research and a high level of scientific interest in this field. In this review, we summarise current knowledge regarding the structure and function of nuclear receptors as principal regulators of gene expression. Emphasis is given to the molecular mechanisms of nuclear receptor-mediated transcriptional activation and repression including recent progress made in this area.

Answer:
absorbs water is a function of the integumentary system. hope it help you.
A function of the integumentary system is to grow new tissues. Thus, the correct option B.
What is the Integumentary system?The integumentary system may be defined as a unique type of system that primarily consists of the skin, hair, nails, and exocrine glands. It is the set of organs that construct an outermost layer of an animal or human body.
The integumentary system plays a significant role in the growth of new tissues within the body. The cells of the skin generally hold the mechanism of renewal or replacement of injured or damaged cells which are present on the epidermis part of a specific organ.
The integumentary system also protects the body from infections, and injuries provide defense against pathogens, etc.
Therefore, a function of the integumentary system is to grow new tissues. Thus, the correct option B.

Answer:
B
Explanation:
What is a living cell?
Answer:
Though they are often debated, there are eight main characteristics that define a cell as living.
The first is genetic code. All living things contain DNA, which is like the instruction manual for life. DNA is contained in each cell, and passed from parent to offspring.
The second is growth and development. Whether by creating more cells or creating more organelles within the cell, all living things grow and develop.
The third characteristic is reproduction. Reproduction can be sexual or asexual, but in the case of single cells, it is asexual.
The fourth characteristic is response. All living things, including cells, react to external stimuli, such as temperature or salinity.
The fifth characteristic is homeostasis. Homeostasis is the condition by which living things maintain a stable internal environment in the midst of an ever-changing external environment.
The last three characteristics go hand in hand, and are sometimes combined, but in my mind they are distinctly separate.
Sixth is consumption, which is taking in food and other materials. A cell specifically takes in molecules such as water or glucose during consumption.
Seventh is metabolism, which is using materials consumed in order to create energy. Living cells use enzymes to break down materials to produce ATP (adenosine triphosphate), which is usable energy.
Finally, all living cells undergo excretion in some form. Some examples in cells include exocytosis and osmosis.
These 8 characteristics, though often controversial, determine a cell as living.

c. Both Photosynthesis and Cellular Respiration
d. Neither Photosynthesis nor Cellular Respiration
