Answer:
Water, ions, glucose, fluids
Explanation:
This is because the nephron have network of cappilaries vessel called glomerulus . This glomerulus filter blood in the kidney to make urine. The hydrostatic force cause the filtrate to be filtered out through pressure.
The nephron also posses tubule which help to return needed or essential substances like protein, ions to the blood and then remove waste products from the blood.

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.

3.2 State whether each of the phrases applies to A only, B only,
both A and B or none. Write down A only, B only, both A and B
or 'none' next to the question number.
For example, 3.2.6 None
3.2.1 Mitosis
A cloning
B chromosomes
3.2.2 Chromosome
A chromatid
B spindle fibre
3.2.3 Phases in the cell cycle
A interphase
B mitosis
3.2.4 Tumour
A benign
B malignant
3.2.5 Bone cancer
A carcinoma
B leukaemia
Answer:
3.2.1 Mitosis - Both A and B
3.2.2 Chromosome - Both A and B
3.2.3 Phases in the cell cycle - Both A and B
3.2.4 Tumor - Both A and B
3.2.5 Bone cancer - B only
Explanation:
1. Mitosis is a process of cell replication , in which one cell divides into two identical daughter cells having the same number of chromosomes. In mitosis, the two new cells are genetically identical. Copies of the chromosome (containing the DNA) are made and distributed equally to each cell. Some organisms such as bacteria reproduce entirely by mitosis.
In cloning, an organism that is genetically identical to another organism is made from that original organism. Cloning can occur naturally or may be done by man artificially. In nature, many organisms produce clones through asexual reproduction for example bacteria produces clones by mitotic binary fission.
Therefore, the phrase mitosis, applies to both A and B.
2. Chromosomes are structures found within the nucleus of cells that contain the genetic material of the organism. The chromosomes are composed two identical structures called chromatids thar are joined together to at a constricted point known as centromere.
During cell division, long fibres extend from the centroiles at the ends of the cell to the centromere of the nucleus in order to pull them apart. These long fibres are known as spindle fibres.
Therefore, the phrase, Chromosome, applies to both A and B
3. The phases in the cell cycle are divided into two major stages : interphase and Mitosis. In interphase, the cell grows and makes a copy of its DNA.
In mitotis, the cell DNA divides into two sets, the cytoplasm divides, forming two new cells.
Thus, phases of cell cycle applies to both A and B
4. Tumours are abnormal growths occurring in any part of the body which may be benign or malignant.
Benign tumours are harmless growth which do not have spread out to other tissues to form various cancers.
Malignant tumors spread out from their point of growth to other tissues leading to cancer in these other tissues and organs.
Therefore, tumors applies to both benign and malignant.
5. Bone cancer refers to abnormal growth of bone cells.
Carcinomas are cancers of the skin and tissue lining of organs.
Leukaemia are cancers affecting the bone marrow, whereby the bone marrow makes abnormal white blood cells, red blood cells and platelets.
Thus, bone cancer only applies to B.

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.
Which of the following is/are parts of the Cell Theory? explantion
Answer:
All organisms are composed of one or more cells. Cells come from other cells by division. Cells are the smallest living things. Eukaryotic cells have evolved from prokaryotic cells.
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.
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.

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 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.
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.

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
These thoughs and facts hopefully answer you question, hope it helps!
