Iron is a component of hemoglobin, which enables it to absorb oxygen from the air we breathe and transport it throughout the body.
What is Hemoglobin?The iron-containing oxygen-transporting metalloprotein known as hemoglobin, often known by the abbreviations Hb or Hgb, is found in the red blood cells of almost all vertebrates as well as some invertebrate organs. The oxygen from the respiratory organs is transported to the rest of the body by hemoglobin in the blood.
The normal ranges for haemoglobin are different for males and females, and they also vary depending on the ethnicity of the population. Additionally, age is a factor, particularly for women.
When you have anemia, your body doesn't produce enough healthy red blood cells to supply your tissues with enough oxygen. Anemia, commonly known as low hemoglobin, can make you feel exhausted and frail.

The only system that does not pass through the thalamus on its way to the cerebral cortex is the __________ system. A. Tactile B. Gustatory C. Olfactory D. Visual.
The cerebral cortex process the information delivered by the thalamus, the information is related to the senses.
The only system that does not pass through the thalamus on its way to the cerebral cortex is the olfactory system.
The systems that pass through the thalamus are:
1. The visual sensation or information passes through the visual occipital cortex. It then delivers the information from the thalamus to the cerebral cortex.
2. The gustatory cortex is the region of the cerebral cortex, which is responsible for the senses of tastes and flavor. It also passes through the thalamus on its way to the cerebral cortex.
3. The tactile system includes the senses of touch. It is the information received through the receptors present on the skin. It also delivers the information to the cerebral cortex via the thalamus.
4. The olfaction system is not involved in the thalamus pathway. The olfactory cortex is present in the temporal lobe, which is not routed through the thalamus.
Thus, the correct answer is Option C.

How does your body respond to a decrease in blood glucose
Answer:
When blood sugar drops too low, the level of insulin declines and and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels back up to normal

In an ecosystem, a deer consumes grass. What percentage of energy will the deer acquire from the grass? 0. 1% 1% 10% 100%.
In an ecosystem, the energy is transferred between the organisms participating in the food webs from producers and consumers.
The percentage of energy transferred to the deer after feeding on the grass is 10%.
The 10% law of the energy states that:
1. The food chain at each trophic level passes or transmits only 10% of the energy and 90% of the energy is lost as heat.
2. The amount of energy at each trophic level decreases, such that the producers if consuming the 100 J of energy, the deers or primary consumers at the first trophic level will have only 10% of the energy.
Thus, the deer will possess only 10% of the energy at each trophic level, following the 10% law.
The correct answer is Option C.

How does a forest fire impact a population of birds that nest in the trees.
Answer:
If a forest fire occurs it will impact a population of birds that nest in those trees because their habitat will be burnt down. This will provoke the birds to find a new habitat which can be hard if the entire forest is burnt down. Additionally resources such as food will be burned down as well.
In the area illustrated, what process is evident over time?
In the area illustrated in the image attached, the biological process which is evident over time is: ecological succession.
Ecology can be defined as the scientific study of the relationship existing between living organisms such as plants and animals with respect to their physical and biological environment (abiotic factor).
In Ecology, ecological succession refers to a process through which the structure of an ecological (biological) community evolves or changes over time.
Generally, there are three (3) main types of ecological succession and these include:
Primary successionSecondary successionCyclic successionFrom the ecological (biological) community illustrated in the image attached, we can deduce that there is an evolution (change) in the species of plants growing over time. This ranges from weeds during the first visit to pine and oak trees during the seventh visit.

5. In a tundra ecosystem, the carrying capacity for arctic hares is about 400 individuals. Which of these events is MOST likely to reduce the carrying capacity for arctic hares in the ecosystem by at least 25 percent?
(A) a severe storm that kills about 100 adult and young arctic hares
(B) a 25 percent decrease in the populations of foxes, wolves, or other predators of arctic hares
(C) the arrival in the ecosystem of a species that competes with the arctic hare for its food
(D) a temporary increase in the arctic hare population to more than 425 individuals
(E) a mutation that introduces a new fur color to the arctic hare population
A temporary increase in the arctic hare population to more than 425
individuals.
Hares are among the primary consumers as they are herbivores while foxes
are secondary consumers which feeds on the hares.Foxes will hunt the
hares for food which will drastically reduce their population
Increasing their population by 425 individuals with the hares having a
population of 400 will surely decrease their carrying capacity in the tundra
ecosystem.

A population of rhinos in Africa is 112. this year there were 17 births and eight deaths in the population. What is the change in population? Do we have a positive, negative, or zero change in population? How many members are in the new population?
Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. work for calculating the new population
Explanation:
Why anti-poaching?Rhinos have inhabited the African continent for over a million years and they play a huge role in their ecosystems. The illegal trade in powders made from their horns, which in some countries in Asia is still considered a medicine or simply a symbol of wealth, nearly led to the extinction of the African rhino.
In 1875, there were still more than 1,000,000 rhinos living in the vast grasslands of Africa. Today the populations of the two species of black rhino and white rhino are estimated to contain about 5,000 and 20,000 animals respectively. The senseless killings continue. Since 2007, the number of rhinos hunted in Africa has increased by almost 9,000%.
It is therefore our call to stop the slaughter of rhinos with all our might.

differences between the structure of the wall of the stomach and the structure of the wall of the ileum
Answer:
Wall of stomach : it has three layers of muscle instead of two. Under these muscle layers is the adventitia, layers of connective tissue continuous with the omenta. The epithelium of the stomach forms deep pits, called fundic or oxyntic glands.
wall of ileum : The wall itself is made up of folds, each of which has many tiny finger-like projections known as villi on its surface. The ileum has an extremely large surface area both for the adsorption of enzyme molecules and for the absorption of products of digestion.
