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.
I think it’s tree am I right?
Answer:
mm yes tre.........
Explanation:
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.

Nuclear Energy is produced by
Answer:
Fission or the act of splitting uranium atoms
Answer:
Nucler fission
Explanation:
Clearly C and D arent correct.
In nuclear fission(A), a uranium atom(mildly radioactive) is split by a nutreon, which realeases nucler energy.
In nucler fussion(B), which only occurs in the sun and stars, two nulcei are combined to make a even bigger nuclei, this does not produce nuclear energy.
Hope this helps :)
what is respiration and the different types
Answer:
It involves inhalation and exhalation of gases. Internal respiration involves gas exchange between the blood and body cells. Cellular respiration involves the conversion of food to energy. Aerobic respiration is a cellular respiration that requires oxygen while anaerobic respiration does not.
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.

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.

A chromosomal mutation is best described as-
A. Mutations that involve changes in the number or structure of chromosomes in a cell or organism.
B. Changes in the “reading section” of a protein code frame that affect the subsequent amino acids.
C. An amino acid substitution that changes all of the subsequent protein codes on the chromosome.
D.a change in the genetic make-up of an organism that causes speciation to occur in a population.
Answer:
A
Explanation:
chromosomal mutation definition. A mutation involving a long segment of DNA. These mutations can involve deletions, insertions, or inversions of sections of DNA. In some cases, deleted sections may attach to other chromosomes, disrupting both the chromosomes that loses the DNA and the one that gains it.
Organism A has blunt teeth, while organism B has sharp ones. Identify the organisms on basis of their feed habit and give another point of difference between these two organisms
Answer:
- Organism A is most likely a herbivore
- Organism B is most likey a carnivore
Explanation:
Based on feeding habit, organisms, usually animals, can be classified into three categories namely: herbivores, carnivores and omnivores.
- Herbivores are those organisms that feed on vegetative matter i.e. plants while carnivores are those organisms that feed on flesh of other animals or organisms. Based on what they feed on, herbivores are adapted to possess blunt teeth (for chewing) like Organism A in this question while carnivores are adapted to possess sharp teeth (for tearing flesh) like Organism B.
Based on the above explanation, organism A is most likely a HERBIVORE while organisms B is most likely a CARNIVORE.
- Another notable point of difference between herbivores and carnivores, which is likely to differentiate organism A and B as well, is that herbivores possess digestive enzyme- amylase in their saliva while carnivores do not. Herbivores need AMYLASE to break down complex carbohydrate (starch) in the plants they feed on.

Explanation:
The normal shape of an enzyme is as shown in structure A. If the enzyme's shape changes to that shown in structure B, what are two consequences of this change? Less binding of substrate more binding of substrate won't follow the lock-and-key pattern of enzyme binding will follow the lock-and-key pattern of enzyme binding a substrate reaction independent of the enzyme structure
Answer:
There is no image showing the shape of an enzyme, however, the question can still be answered based on basic understanding. The answers are;
- Less binding of substrate
- won't follow the lock-and-key pattern of enzyme binding
Explanation:
An enzyme is a biological catalyst that regulates the rate of chemical reactions in living systems. Enzymes are proteinous in nature and every protein is made up of an amino acid sequence. The amino acid sequence forms a three-dimensional shape that determines the functionality of the enzyme.
Enzymes catalyze reactions by binding to their substrates in a lock and key pattern. This makes enzymes substrate-specific. If the enzyme's normal shape changes, the following will occur:
- Less binding of substrate
- won't follow the lock-and-key pattern of enzyme binding.
what is the function of the seed producing in mosses plants?
Explanation:
Ecologically, mosses break down exposed substrata, releasing nutrients for the use of more complex plants that succeed them. They also aid in soil erosion control by providing surface cover and absorbing water, and they are important in the nutrient and water economy of some vegetation types.

Answer:
3.2.1. A only
3.2.2. A only
3.2.3. A and B
3.2.4. A and B
3.2.5. None
Explanation:
- 3.2.1
Mitosis is a kind of cellular division that produces two genetically identical daughter cells. Whereas, cloning is a technique used to create identical cells. This means that mitosis applies to cloning.
- 3.2.2
A chromatid is a half of a replicated chromosome. Together, a replicated chromosome is called SISTER CHROMATIDS. One of them is called a Chromatid. Spindle fibre is a structure involved with the division of the genetic material during cell division.
- 3.2.3
The cell cycle consists of two stages interphase and mitotic phase. Hence, interphase and mitosis are part of the cell cycle.
- 3.2.4
A tumour is a cancerous mass of cells. Tumour can either be BENIGN i.e. not capable of spreading to other parts or MALIGNANT i.e. capable of spreading to other parts.
- 3.2.5
Cancer is an uncontrolled division of cells and can occur in virtually all organs of the body. Bone cancer is a type of cancer that affects the bone cells. However, carcinoma (starts in the skin) and leukaemia (blood cancer) are unrelated to bone cancer.

What’s the answer please??!!!
Answer:
A
Explanation:
Almost all embryos of vertabrites look the same at early embryo stages, even humans to other organisms. This is because they all have a common ancestory, adn orginated from a organism with an embryo that looked like this.
It is clear it cannot be the other answers for the folowing reasons:
The organisms will definatly not look the same, considering they are birds and reptiles. The 2nd answer speaking of geography isnt very accurate, and cannot be determined because as I said above, any vertibrate embro looks very similar, and close geopgraphy isnt what made them look similar.
Again, all vertabrites have the same embryos, and that is a phylum. Not a genus. There are many genus in a phylum, and the ecaxt one cannot be determines.
As I said above, HUMANS look simiar to BIRDS and REPTILES, but clearly grow to be much different.
Answer:
A: the organisms share a common ancestory
