blood type can receive Rh+ or Rh- blood
Answer:
People with Rh- blood can give blood to both Rh- and Rh+ recipients. However, those with Rh+ blood cannot give to Rh- recipients. If a person receives blood from someone with an incompatible blood type, it can cause a life threatening immune system reaction.

Explanation:
A chromosome is a strand of DNA that is encoded with genes. In most cells, humans have 22 pairs of these chromosomes plus the two sex chromosomes (XX in females and XY in males) for a total of 46. The word chromosome was originally coined in German from the Greek words khroma, meaning color, and soma meaning body.
Red squirrels and gray squirrels have been the native species on an island for many years. A few years ago, black squirrels entered this island. The black squirrel is an invasive species. Invasive species aren't native to the ecosystem. They move into an ecosystem because of natural changes or human intervention. Red squirrels and black squirrels have identical food requirements, but gray squirrels have a different diet. What three effects will these events have on the island's squirrel population?
Answer:
1. There will be direct predation of species.
2. There will be competition for limited resources like breeding sites, prey.
3. Transmission of diseases or they can cause danger to the native species.
Explanation:
Invasive species are species of organisms that are not natural to an ecosystem and move to an ecosystem because of natural changes and human intervention. Islands are prone to the invasion of invasive species because they don't have predators and there is no competition that control populations in their ecosystem. The invasion of black squirrels will lead to competition for limited resources like breeding sites or prey, the black squirrels will begin to predate other squirrels because they have different nutrients requirements and they can transmit diseases to other squirrels if they are carrier.

Which traits would Aristotle have used to classify sharks? Choose more than one answer.
Answer:
The main trait that was different between sharks 14 and 9 was that shark 14 (Mobulidae) has a front with two points that look like horns, whereas shark 9 (Dasyatidae) has a front with no points that look like horns.
Explanation:
The traits that Aristotle would have used to classify sharks are :
Front with points ( hornlike )Front without points Sharks classificationSharks whose front have two points like horns are classifed by Aristotle as sharks 14 (Mobulidae). whlie sharks whose front does not have two points like horns are classifiesd as sharks 9 ( Dasyatidae ). hence the traits that would have been used by Aristotle to classify sharks is the presence of points at the front.
Hence we can conclude that the traits that Aristotle would have used to classify Sharks are Front with points and front without points.

Complexity is a measure of how difficult it is to understand something. What is an example of complexity in the natural world?
Answer:
Answer:
Multicellular organism is the example of complexity of the natural world.
Explanation:
Multicellular organism such as human which is made of billions of cell. Each cell perform a specific function. The function of one organ is different from the other organ. For example, brain of human is made of millions of neurons which takes instructions from brain to the organs and bring messages from organs to the nervous system in the form of electrical impulses. In short every system in our body is full of complexity.

How is the epithelium suited for the substances ?
Answer:
Epithelial tissue is composed of cells laid together in sheets with the cells tightly connected to one another. Epithelial layers are avascular, but innervated.
Epithelial cells have two surfaces that differ in both structure and function.
The epithelial cells are nourished by substances diffusing from blood vessels in the underlying connective tissue. One side of the epithelial cell is oriented towards the surface of the tissue, body cavity, or external environment and the other surface is joined to a basement membrane. The basement layer is non-cellular in nature and helps to cement the epithelial tissue to the underlying structures.

BY USING FOREST WISELY;
It was learnt that people are cutting trees at an worrying rate.This problem is disturbing because ;
1)Those trees are responsible for releasing of oxygen and they made up at least a quarter of the world population.
2) Those trees of the world make up of portion land species by more than forth or fifth portion.
There are also economic implications as a result of trees been cut down, when there is no availability bot trees , it could result to situation whereby there would be scarce of resources for industries as well as
hike price of paper in market, regardless of this trees are needed for manufacturing of important materials such as usage in making houses and others developments or growth
Therefore, all the afformentioned economic concern result in economics delay scientists' first attempts.
COMMUNITY CONSERVATION;
It was learnt that there is to the forest that those gorilla habitated, those human being that reside in those region reside there so they can practice their farming because their is available land there. They also reside there because of housing.
These gorillas were affected as a result of the destruction made to their habitat as well as the activities of the poachers that hunt them for production of the and skin.
There are adverse effect of the obliteration of the gorilla from on the society, it can result to having reduction in tourism in country such as
Uganda as well as Rwanda, as result of this the means of livelihood of people in that part could be affected because there would be Reduction in profit making. Hence the reason behind the increase in number gorillas in the region, because they know they know that those gorilla influence the number of tourist that comes there and the revenue that is generated through this tourism.
The article 'By using Forest Wisely' can be summarised as:
People are cutting trees at the wrong rate and trees play a crucial role in an ecosystem. The trees produce oxygen and they made up at least a quarter of the world population.The trees occupy the fourth or fifth portion of the land organisms.In the absence of trees, the ecosystem will fail and the organisms dependent on them will eventually die. The resources available from the trees will be scarce and the factories and industries that are dependent on trees will no longer be available. Trees are required for manufacturing important materials.The article 'Community Conservation' can be summarised as:
In the article, it was mentioned that the human populace urbanized the land region where gorillas were habituating. The humans occupied the space to practice farming and make houses. The population of the gorillas was disturbed and diminished. The hunting of gorillas by poachers was also reduced. The people of Uganda and Rwanda also suffered reduction tourism and conservation of wildlife. Gorillas influence the number of tourists, therefore, the destruction of their habitats led to a reduction in profit-making.Therefore, all the mentioned economic concerns result in economics delaying scientists' first attempts.
