Answer:
Using your gloved hand to apply pressure on the wound to control bleeding. b. Direct pressureBleeding that can be seen coming from a wound. a. External bleeding The escape of blood from an artery, vein, or capillary inside the body. d. Internal bleeding A tight band placed around an arm or leg to constrict blood vessels in order to stop blood flow to a wound. g. TourniquetBlood vessels that carry blood from all parts of the body to the heart. f. Veins Vessels that transport blood to the capillaries for distribution to the cells. e. ArteriesA bandage applied snugly to maintain pressure on the wound to control bleeding. c. Pressure bandageExplanation:
Direct pressure is a technique used to stop the bleeding on the wound. The person should place both hands over the wound and press firmly till doctors arrive. With this first aid technique, we prevent excessive blood loss, which can cause worse problems in the future.
There are two types of bleeding, external and internal. In the first one, the skin opens, and blood comes out to the exterior. In the second one, the skin is not open, so the blood does not come out to the exterior, but blood goes to tissues around the broken vessel due to an internal injury.
A tourniquet is a first-aid technique use to stop blood flow and prevent that the injured person bleeds out till death. A band, a piece of shirt, or a belt should go around the limb and tie it hard to stop the blood flow and allow the patient to arrive at the hospital. It is a technique usually use when there is a wound that affects the main vessels.
There are different types of vessels. They change in size and structure. Veins are the vessels that carry blood back to the heart, where it will go to the pulmonary circuit to be oxygenated. Arteries will take the oxygenated blood from the heart to the rest of the body. The arteries branch into small vessels called arterioles, and the arteries branch into capillaries which will give oxygen to the cells.
A pressure bandage controls bleeding and prevents the injury from being contaminated. The pressure bandage does not restrict blood flow as a tourniquet.

Complete question:
Scientists have proposed more than two dozen ways to define species. One commonly used definition, called the biological species concept, holds that populations belong to the same species if they can contribute genes to a common gene pool. Reproductive barriers block gene flow between different species. Gene flow between populations tends to hold the gene pool of a species together.
Part A - Comparing species definitions
Three of the most prominent definitions of species are the biological species concept, the phylogenetic species concept, and the morphological species (morphospecies) concept.
Drag each characteristic to the appropriate bin based on the species concept(s) to which it applies → You will find this in the attached files
Answer:
Not applicable for extinct species → Biological Based on evolutionary history → Phylogenetic Relies on similarities in structure → Morphological Accommodates asexual reproduction / Species acceptance criteria can be subjective → Morphological and PhylogeneticUsed by scientists in classification → Morphological, Phylogenetic, and BiologicalExplanation:
The biological concept states that species are population groups that -in a real or potential way- can mate and reproduce, but are reproductively isolated from other groups.
Individuals belonging to a species cannot reproduce with members of other species.
This biological concept has limitations. Its application might present difficulties in concern with asexual reproduction species, such as bacteria, rotifer, cnidarians, plants, and etcetera.
Besides, this concept cannot be applied to the past because it is difficult to deduce reproductive capability between extinct species.
Finally, this concept is not adequate concerning hybridization zones, something to be expected considering evolutionary processes. This is the reason why it has been less accepted by botanists, as some plant species hybridize with other species.
The phylogenetic species concept defines species on a determined time and through time, and these are the horizontal and vertical species concepts, respectively. The species group is considered to be the less inclusive monophyletic group.
According to the phylogenetic concept, a species is a monophyletic group whose organisms share synapomorphies.
The establishment of species relies on molecular markers.
The morphological species concept defines species according to the shared morphological characteristics shared by all the members of the species. It is a descriptive method to separate species.
When a group differs considerably at a morphological level from another group, it is defined as a different species.
Some limitations might emerge from this species concept. It does not consider variability among individuals,
Individuals of the same species might be polymorphic, exhibiting morphological differences between organisms. These individuals would be considered to be different species following the morphological concept. Some different species might be morphologically similar, despite being different. These species might be considered as one following the morphological concept.A 7th grade teacher asked students to engage in an argument regarding human impact on a national forest ecosystem that was home to mountain lions, coyotes,
and bobcats as well as about 3,000 deer. The deer ate grass, and the mountain lions, coyotes, and bobcats ate deer. Hunters began killing
large numbers of
mountain lions, coyotes, and bobcats. About 20 years later the deer population had increased to about 100,000. The teacher asked the students to explain why
the population of deer increased. Which student's argument most accurately explains the increase in the deer population?
O A. Student 1: The number of deer increased because deer populations are always increasing, even when there are lions, coyotes, and bobcats preying on
them.
O B. Student 2: The number of deer increased because without lions, coyotes, and bobcats, the deer lived longer and had more offspring that also lived
longer.
c. Student 3: The number of deer increased because with fewer mountain lions, coyotes, and bobcats, the deer had more food available to eat
D. Student 4: The deer population increased because with fewer lions, coyotes, and bobcats, there was less competition within the deer population.
Answer:Student 4
Explanation: Because if the mountain lions, coyotes, and bobcats decrease they arent enough to prey on the deer which causes the deer population to be able to reproduce over time.

What is embedded in the phospholipid bilayer that helps in the movement of larger molecules ?
A.Channel/Transport proteins
B.Salt
C.Water
D.Fats
Answer:
[tex]\boxed {\boxed {\sf A. \ Channel/Transport \ proteins}}[/tex]
Explanation:
The phospholipid bilayer is also known as the cell membrane. It covers cells and regulates the transport of substances. Certain ones can pass and others cannot, depending on certain factors like size and polarity.
Smaller substances tend to diffuse or move across the membrane quite easily. However, larger molecules have a much harder time. Many depend on special proteins embedded in the membrane. These are called transport proteins and they form a channel so large molecules can still move in or out of the cell.
So, salt, water, and fats do not contribute to the movement of larger molecules, but channel or transport proteins do and choice A is correct.

When carbon dioxide is dissolved in the ocean, what can it be turned into?
A. Fossil fuels
B. Seashells
C. Nitrates
D. Zooplankton
I think its B. seashells?
Explanation:
Organisms in the ocean take Carbon Dioxide and turn it into carbonate CO 2/3
Carbonate is often combined with ions like CA 2+ and MG 2+
The Calcium Carbonate makes up the hard structures of corals, and sea shells. The amount of Carbon in the Coral reefs far exceeds the amount of Carbon Dioxide dissolved in the oceans.
What is the relationship between the temperature of internal material and volcanic eruptions?
plz help.....
Answer:
Direct relationship.
Explanation:
There is direct relationship between the temperature of internal material and volcanic eruptions because the temperature of internal material causes the volcanic eruptions. The temperature of the internal material puts pressure on the rocky surface and the gases that releases from heating processes will cause pressure which leads to the eruption of the volcano so we can say that there is a direct relationship between temperature and eruption.

________ thousands of tiny projections that add even more surface area to villi
Answer:
Each villus, in turn, has thousands of even smaller projections called microvilli (singular: microvillus).
Explanation:
The villi contain capillaries, which are tiny blood vessels. Nutrients are absorbed into these capillaries across the surfaces of the villi and microvilli. Because there are millions of these tiny projections, they greatly increase the surface area for absorption.

Describe what the male beetle has to do In order to successfully mate with the female
Answer: they would maybe have to fight with the other beetles to tr and get the females attention
Explanation:
pls mark brainliest
The male beetle must struggle to successfully mate with the female if where they go there is more than one male courting the female.
How do beetles mate?Female beetles of this species dig tunnels in the dung, where males mate with them. If a male enters a tunnel that is already occupied by a rival, they will fight, trying to pull the other out.
With this information, we can conclude that the male beetle must struggle to successfully mate with the female if where they go there is more than one male courting the female.

List one abiotic and one biotic factor that humans use to limit pest population.
Answer: temperature, animal
Explanation:
Abiotic factor is a non-living environmental factor like soil, water, temperature, humidity, sunlight, and others. Biotic factor is a living factor including living beings like microbes, humans, insects, and others. A limiting factor is the one which can reduce the abundance and growth of living organisms. A limiting factor can be abiotic or biotic.
Temperature is one of the abiotic factors which can reduce the abundance of pests. Increase in temperature can kill pests, which cannot tolerate the rise in temperature. Animal that feed on pests can also reduce the abundance or population of the pests. Like lizards, frogs, and others.
