They share common ancestry

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!

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​

Answers

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.

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

Answers

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.

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

Answers

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.

How is density affected when the salinity increases?

Answers

Answer:

The density of water increases as the salinity increases. The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point. The density of seawater is increased by increasing pressure

[tex] \huge \sf \green{Question}[/tex]

How is density affected when the salinity increases?

[tex] \huge \sf \green{Answer}[/tex]

When salt is dissolved in fresh water, the density of the water increases because the mass of the water increases.

Salinity describes how much salt is dissolved in a sample of water. The more salt there is dissolved in the water, the greater its salinity. When comparing two samples of water with the same volume, the water sample with higher salinity will have greater mass, and it will therefore be more dense.

Answers

Answer:

Original sentence: When new information does not support a scientific theory, the theory  may be revised or sometimes rejected.  

New changed sentence: When the results of the experiment do not support a hypothesis, the hypothesis must be revised or rejected to state a new scientific theory.

Explanation:

The scientific theory is a conceptual framework used to explain facts or phenomena and to make predictions.

The theory is fundamental to science because it allows scientists to organize and understand observations.

The construction of a theory begins with a hypothesis. The scientist believes that a phenomenon occurs in a certain way, so he/she performs observations under the scientific method to prove that his/her hypothesis is valid or not valid. The systematization of the observations and the empirical data collected might derive from a scientific theory that explains the analyzed phenomenon.

A scientific theory is a knowledge that has been contrasted in several ways.

describe two ways to transfer electric charge

Answers

.Answer: conduction or polarization

Answer:

conduction, friction

Explanation:

Friciton: When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged.

Conduction: During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. In order for the neutral sphere to become negative, it must gain electrons from the negatively charged rod.
