Explanation: "Science is the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment

Answer:because they are not in the same place

Explanation:

Answer:

Positive Human Interaction When people build dams channeling off large bodies of water, the water builds up along the edge of the lake, pond, or stream creating very fertile soil from the constant watering and these areas on the outside of lakes and ponds are used by humans for growing and farming crops.

Explanation:

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.

.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.

Answer:

Conductors

Explanation: the substances which have a large number of free electrons and offer a low resistance are called conductors

Answer:

false

Explanation:

The statement "Energy cycles through ecosystems because it returns to the Sun" is definitely false.

An ecosystem may be defined as a type of place or an area where members of different species live together and interact with one another for the purpose of food, shelter, space, and mating partner.

The ultimate source of energy for the living being is delivered by the sun. But the sun never takes this energy in any form. It is true that the energy cycle in the ecosystem but does not passes to the sun. It gets cycled through living organisms like plants, animals, and microorganisms.

The plants captures the energy from sunlight through photosynthesis, herbivores take energy from plants, carnivores take energy from herbivores, and the microorganisms get energy from dead and organic matter.

Therefore, the statement "Energy cycles through ecosystems, because it returns to the Sun", is definitely false.

I know this is old, but just in case anyone else needs it

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.

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.

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.

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.

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.
