Answer:
A high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.
Viscosity refers to the thickness of blood. This thickness is caused by the number of red blood cells. Thick blood travels through blood vessels at a slower rate than thin blood.
True or False: Atmospheric nitrogen (N2 gas) is easily taken up and used by plants and animals.
Answer:
False
Explanation: im only in the 8th grade
A plant requires minerals and nutrients for its growth. There are two types of nutrients on the demand of requirements, These nutrients are as follows:-
Micronutrient MacronutrientPlants totally depend on nitrogen for their functioning but atmospheric nitrogen is poisonous to the plant.
Hence there are various microbes that convert the atmospheric nitrogen to its amides which are non-poisonous and easy to absorb.
Hence, the statement is wrong.

B. protein
- DNA - RNA → DNA
C. DNA - RNA DNA protein
D. RNA - protein - RNA - DNA
HIV is a retrovirus whose sequence is RNA DNA → RNA protein which it uses as part of its reproductive cycle. So, the correct option is A.
What is HIV?HIV stands for Human Immunodeficiency Virus which is defined as a virus that attacks the body's immune system. If HIV is not treated, it can lead to AIDS which stands for acquired immunodeficiency syndrome. There is currently no effective cure, while once people have HIV, it remains with it for life.
HIV can spread through sexual contact, illicit injection drug use or sharing needles, contact with infected blood, or from mother to child during pregnancy, childbirth or breastfeeding. HIV is a retrovirus whose sequence is RNA DNA → RNA protein which it uses as part of its reproductive cycle.
So, the correct option is A.

What are the 3 main processes common between terrestrial and aquatic ecosystems?
Answer:
Three main processes that are common between these are that they both make food through photosynthesis, they both perform transpiration, and they both need sunlight in order to process chemical energy.
I really hope this helped and have a great day! :)
The process that are seen in both terrestrial and aquatic ecosystems are;
Transpiration process
Photosynthesis for food synthesis
Energy through sunlight.
An ecosystem can be regarded as geographic area which contains plant as well as animals with other organisms and weather and landscape and they all carried out different functions so that bubble of life is formed.Ecosystem could be terrestrial as well as aquatic ecosystems.An aquatic ecosystem can be regarded as types of ecosystem containing body of water. In contrast to terrestrial ecosystems that is associated to land, there are Communities of organisms that their dependent is on each other as well as the environment all live in aquatic ecosystems.Aquatic ecosystems could contains body of oceans as well as lakes rivers, and stream.Terrestrial ecosystem can be regarded as community of organisms that dominate land, as well as interactions that exist between biotic as well as abiotic components in a given area. Some of terrestrial ecosystems are tundra, taigas as well as temperate deciduous forests and tropical rainforests.Some of the processes that can be attributed to both terrestrial and aquatic ecosystems are;
Making of their food could be through photosynthesis, this is the process whereby plant makes their food through the energy from sunlight.Sunlight is required as a source to process energy. Transpiration can be regarded as process involving movement of water through a plant, this could also encompass the evaporation of this water from aerial parts which could be in the leaves as well as stems and flowers.Therefore, both terrestrial and aquatic ecosystems have some process in common.

Answer:
six
Explanation:

What role does reproduction play in both natural and artificial
selection?
Answer:
It allow organisms to pass down their traits to the next generation.
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest.
Artificial selection is also known as selective breeding and it is a process that involves humans (breeders) selecting the animal or plant with desirable traits in order to reproduce favorable offspring having phenotypic traits.
Hence, the role which reproduction play in both natural and artificial selection is that it allow organisms to pass down their traits to the next generation.

Name 3 characteristics of each physical state of matter.
Solid:
Liquid:
Gaseous:
Answer:
solid: Has a definite shape and volume. liquid: Has a definite volume, but take the shape of the container. gas: Has no definite shape or volume. change of state: When matter is converted from one of the three states (example: solid, liquid, or gas) to another state.
Explanation:
Answer:
Solid:
High Density
Definite mass, volume, and shape
Solids are incompressible and rigid
Liquid:
No definite shape (takes the shape of its container)
Has definite volume.
Particles are free to move over each other but are still attracted to each other.
Gaseous:
They are easy to compress
They expand to fill their containers
They occupy far more space than the liquids or solids from which they form
