Explanation:
What is the volume of a square pyramid with a base edge of 14 m and a slant height of 25 m
Answer:
length of base(l) = 14m
slant height (s)=25m
we know,
slant height(s)=√(l/2)^2 + h^2
or, 25= √(14/2)^2+ h^2
or, 25 = √49+h^2
or, 25^2 = 49+h^2
or, 625 = 49 + h^2
or, 625-49=h^2
or, √576 =h
h=24
Therefore vertical height (h)= 24m
Again,
Volume of square pyramid (v) = 1/3 L^2h
or, v =( 1/3) 14^2×24
or, v= 4704 / 3
Therefore, V= 1568 cubic meter.
What colour does bicarbonate indicator change to in presence of oxygen and carbondioxide
Answer:yellow
Explanation:
Hydrogen bicarbonate is an indicator that is use to test the amount of carbondioxide and oxygen in the aquatic body. It's main color is red.
It normally turn to yellow when there is more carbondioxide present in the atmosphere of the water body. It turn yellow when respiration is much because carbondioxide is exhaled out.

Explanation:
Infer why base substitutions in the third position are least likely to cause a change in the amino acid for which it coded.
Answer:
Because of the codon oscillation.
Explanation:
The formation of codons is susceptible to the occurrence of oscillation, which is the term that corresponds to the fact that many codons have synonyms in the third position, that is, in the third letter. For example, the codon CUA, which represents leucine, will also represent leucine if it is presented in CUU, CUC and CUG forms, due to the oscillation in the third position. This allows the tRNA to recognize any of these codons and pair with the anticodon smoothly and without errors.

Answer:
blood group
Explanation:
(b) Identify the dependent variable in the experiments. Identify a control group missing from the second experiment. Justify the need for this control group in the second experiment.
Hello. You have not submitted the experiments to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
A dependent variable is one that is influenced by an element, in order to present a result, that is, it is a variable that does not establish itself, being dependent on another variable to establish itself. An example of a dependent variable can be seen in an experiment that seeks to determine the differences in growth rates of bean plants that were fertilized with different organic fertilizers. As you can see, this is an experiment where the different organic fertilizers influence differences in the growth rate of bean plants. Thus, the growth of these plants depends on the fertilizer, this growth being the variable dependent on the experiment.
A control group, in turn, is an element of the experiment that does not receive the element that is being tested in the same experiment. The control group is important, because it allows the researcher to see the results of a system where the tested element does not exist, thus being able to determine the real differences that the tested element is capable of causing. Using the same example presented in the paragraph above, we can see that the different organic fertilizers are the elements tested in the experiment. These fertilizers will be applied to the plants, however it is important that at least one of these plants does not receive any fertilizer, so that the difference between a system with fertilizer and a system without fertilizer can be evaluated. This plant that received no fertilizer is the control group.

Answer:
1. Tissues
2. Heterotrophic
3. Body cavity
4. Eukaryotes
5. Radial symmetry; bilateral symmetry.
Explanation:
1. All animals except sponges have tissues, groups of cells that work together to perform a specific function.
Sponges are sea animals which are found attached to surfaces. They are multicellular and heterotrophic like other animals, but they lack true tissues and organs.
2. All animals eat other organisms in order to gain building materials for the body. This makes them heterotrophic, since they obtain necessary energy and chemical building blocks from the environment.
Heterotrophs are organisms that cannot manufacture their own food, but obtain it from their environment instead.
3. One key adaptation of animals was the evolution of a body cavity, a fluid-filled gap between the outer wall of the body and the outer wall of the digestive system.
A body cavity is a space found inside the body that is filled with fluid and which holds and protects internal organs. There are several cavities found in the human body and they are separated by membranes as well as many other structures.
4. All animals are eukaryotes, organisms with cells that are relatively large, complex, and contain membrane-enclosed organelles such as the nucleus.
5. Cnidarians are the only animal phylum to display radial symmetry, meaning that their bodies can be divided any way through the center point to yield two even halves.All other adult animals display bilateral symmetry, meaning that their bodies can only be sliced lengthwise through the midline to produce two even halves.
Galaxies that are moving away from earth are?
Answer:
The galaxies are moving away from Earth because the fabric of space itself is expanding. While galaxies themselves are on the move — the Andromeda Galaxy and the Milky Way, for example, are on a collision course — there is an overall phenomenon of redshift happening as the universe gets bigger.

When there is no pattern to a
population's growth, it is known as
A. irregular
B. stable
C. irruptive
D. cyclical
When there is no pattern to a population's growth, it is known as stable. The correct option is B.
What is population growth?The rise in the number of people on Earth is referred to as population growth. The majority of human history saw a relatively steady population size. Energy, food, water, and medical care, however, became more accessible and dependable as a result of innovation and industrialisation.
The predicted population expansion is due in part to factors like an increase in young, unmarried mothers, high fertility rates for specific ethnic groups, and a lack of access to contraception and sexual education.
When age-specific fertility and mortality rates are constant over a long period of time, there is a stable population growth.
Contrarily, an irregular population increase is one in which there is no structure and the population size behaves chaotically.
Thus, the correct option is B.

Is the following sentence true or false? During meiosis, the two alleles for each gene stay together.
Answer:
False
Explanation:
During meiosis, a cell goes from a diploid stage to a haploid stage. So no, the alleles do not stay together.

OA Phenolphthalein
O B. Luminol
OC. Fluoresceln
OD HemaStix
Reset Next
Answer:
The correct answer is - D. Hemastix
Explanation:
HemaStix is a blood reagent test to test the blood present in a sample with the help of strips of tetramethylbenzidine and hydrogen peroxide. It is a presumptive color test. A presumptive color test that detects blood.
In this test, the plastic pad of TMB and hydrogen peroxide gets a sample from a wet swab, initially, it gives yellow color but if there is blood and it touches with blood it will turn green or blue-green. It does not require to destroy the DNA of the blood cells.
Tadpoles must undergo a major metamorphosis to become frogs. This change includes reabsorption of the tail, growth of limbs, calcification of the skeleton, increase in rhodopsin in the eye, development of lungs, change in hemoglobin structure, and reformation of the gut from the long gut of an herbivore to the short gut of a carnivore. Amazingly, all of these changes are induced by triiodothyronine. What is the most likely explanation for such a wide array of effects of triiodothyronine
Answer:
The most likely explanation is that different body parts have different tissues which in turn have different thyroxine receptors. This leads to different signal transduction pathways.
Explanation:
The triiodothyronine absorption through different tissues lead to different signal transduction pathways.
