T/F : the kidneys convert vitamin d and thereby assist calcium homeostasis.
Answers
True. The kidneys play a crucial role in calcium homeostasis by converting inactive vitamin D (calcidiol) into its active form, known as calcitriol.
Calcitriol is a hormone that regulates calcium absorption from the intestines, promotes reabsorption of calcium in the kidneys, and regulates the overall calcium balance in the body.
When blood calcium levels are low, the kidneys increase the production of calcitriol, which stimulates the absorption of dietary calcium in the intestines, reducing calcium loss in urine, and promoting calcium uptake in bones.
This conversion of vitamin D in the kidneys is an essential mechanism for maintaining calcium homeostasis in the body.

Areas of the sample turn a very blue-black. Based on this analysis, you determine thatA. the sample contains an abundance of simple sugars which are found in vascular tissue.B. the sample contains a waxy substance and is therefore dermal tissue.C. the sample contains starch and starch is stored in ground tissue.D. the sample contains an abundance of photosynthetic pigment and is therefore dermal tissue.E. the sample contains many proteins and could be from any of the three tissues.
Answers
Based on the analysis of applying iodine to the sample, the correct answer is C. The sample contains starch and starch is stored in ground tissue.
Iodine is an indicator that stains the cell walls of the plant sample and turns blue-black in the presence of starch. Starch is a form of carbohydrate that is stored in the ground tissue of plants. Thus, the sample containing starch is an indication that it is from the ground tissue.

Answers
The correct answer is: None of the above are true. Crop rotation is the practice of systematically changing the crops grown in a specific area over different seasons or years.
It involves the rotation of different crop species or plant families in a particular sequence to improve soil health, manage pests and diseases, and optimize crop productivity.
The options provided in the question do not accurately describe the concept of crop rotation.
- The first option describes the practice of changing the location of crops within a garden, which is more related to crop placement or intercropping, rather than crop rotation.
- The second option suggests growing the same crop in multiple parts of the garden simultaneously, which is not a rotation but rather a spatial arrangement technique.
- The third option mentions planting several batches of the same crop with staggered planting dates, which is more related to successive planting or staggered planting, not crop rotation.
Therefore, none of the provided options accurately describe the concept of crop rotation.

a pure strain goat with blacked colored fur was crossed with a pure strain goat with white colored fur all the offspring had black colored fur.
i) with the aid of a genetic diagram, determine the phenotypic ratio of the f2 generation if the offspring are selfed .
ii) what would be the outcome of mating a black heterozygote offspring from the f2 generation with the original black colored parent
Answers
i) If a pure strain black goat (BB) is crossed with a pure strain white goat (bb), all the offspring in the F1 generation will be heterozygous black (Bb). If these offspring are selfed (crossed with each other), the phenotypic ratio of the F2 generation will be 3 black: 1 white.
ii) If a black heterozygote offspring from the F2 generation (Bb) is mated with the original black colored parent (BB), all of their offspring will be black. Half of them will be homozygous dominant (BB) and half will be heterozygous (Bb).
Here's a genetic diagram to help you visualize this:
```

after taking a bite of pizza, sensory receptors are stimulated in your mouth. what is the order of information flow that results?
Answers
Correct order of information flow is :Stimulation of sensory receptors → impulse sent to CNS → sensation → perception.
A significant job of sensory receptors is to assist us with finding out about the environment around us, or about the condition of our inner environment. Various kinds of upgrades from shifting sources are gotten and changed into the electrochemical signs of the sensory system. This cycle is called tactile transduction. This happens when a boost is identified by a receptor which creates a reviewed expected in a tactile neuron.
On the off chance that sufficient, the evaluated potential makes the tactile neuron produce an activity potential that is transferred into the focal sensory system (CNS), where it is coordinated with other tangible data — and in some cases higher mental capabilities — to turn into a cognizant view of that upgrade. The focal incorporation may then prompt an engine reaction.

How does a substance across the cell membrane in diffusion?
Answers
A substance crosses the cell membrane in diffusion by passive transport.
Passive transport is a process of moving substances that does not require energy. This transport occurs due to differences in concentration between substances or solutions.
Diffusion is the movement of substances, whether solid, gas or liquid, with or without passing through a membrane, from an area of high concentration to a low concentration. The process of diffusion is a process of moving substances without requiring energy and is very important for the process of transporting substances in living bodies. For example, the process of taking oxygen in single-celled animals is taken from the environment through passive transport by diffusion because the concentration of O2 in the air is higher than inside the cell.
