Give two examples of adaptations that can help a species survive
please fast
Answers
Answer:
Explanation:
Species can have multiple adaptations such as either structural or reproductive adaptation.
Example of structure adaptation for animals would be for giraffe. Their long neck allow them to reach for food high up in the trees. They have adapted to their environment.
Example of reproductive adaptation would be for flowers. The reasons plants have bright colored flowers is so that they can attract insects, birds or even bats which can inadvertently transfer pollen from one plant to another.

In contrast to cooperative hunting, which are benefits of herding only? Check all that apply.
O foraging
reproduction
O divison of labor
O protection
O aerodynamic efficiency
O hydrodynamic efficiency
Answers
Answer:
reproduction; protection
Explanation:
Herd behavior is a type of cooperative behavior where individuals function collectively without the need for a centralized direction by gathering into groups with other individuals of the same species. This behavior provides protection from predators, and it is also used for finding food and for having easier access to mates. Herd behavior may be adaptively advantageous, for example, by increasing the effective vigilance of the herd as a whole and also may confuse/intimidate predators. Different animals exhibit a herd behavior including, among others, bird flocks and fish schools.

Answer:
Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect. Some examples include height, skin color, eye color and weight.
- In polygenic inheritance the "dominant" capital genes are additive, each capital gene adding one unit of color to the genotype.

Elephants live grouped in herds. This is why it is so difficult for a lone elephant living at a circus or exhibit. What type of population distribution do we call animals that live in herds, schools or other groups?
A
random
B
uniform
C
clumped
D
density cluster
Answers
Answer:
clumped
Explanation:
Uniform dispersion is observed in plant species that inhibit the growth of nearby individuals. Random dispersion occurs with dandelion and other plants that have wind-dispersed seeds that germinate wherever they happen to fall in a favorable environment. Clumped dispersion is seen in plants that drop their seeds straight to the ground, such as oak trees, or animals that live in groups, such as schools of fish or herds of elephants.

You went running on a hot day. After your run, you sit down and feel very warm. How is homeostasis reacting?
Answers
Answer:
When you run, your muscles use energy and contract. This contraction and use of muscle fibers produces heat, lactic acid, and carbon dioxide. Your body will attempt to correct homeostasis by sweating to cool down your body (When the water in your sweat evaporates, it takes some heat energy with it), you breath harder to get rid of the excess carbon dioxide, and your blood attempts to clear the lactic out of your muscles.
In many large mammal populations, highways can be barriers to movement - individuals rarely cross them. One solution to this problem has been to install overhead bridges for wildlife to safely cross. The goal is to increase gene flow between the populations on either side of the highway. Which of the following would you expect to see if the bridge is successful in its goal?
a) The two populations would have different mutation rates
b) We would see fewer heterozygotes in both populations
c) Higher levels of drift would occur after the bridge is installed
d) The two populations would become more genetically similar
e) Both populations would decrease in size
Answers
Answer: c. Higher levels of drift would occur after the bridge is installed
Explanation:
Based on the information given in the question, if the bridge is successful in its goal and overhead bridges are installed for wildlife to safely cross, then there'll be higher levels of drift after the bridge is installed.
Since the highways are barriers to the movement of the wildlife, overheard bridges will bring about movement on the other side of the highway and this will result in and increase in drift between both parts of the highway. This will also help in the increase of gene flow between the populations.
Therefore, the correct option is C.
how does the method of obtaining energy for fungi differ from that of plants and animals?
Answers
Answer:
From animals they need energy to get it fungi they can make it
Explanation:
Answer:
Fungi obtain their energy from absorbing either dead or living organisms.
Explanation:
Fungi are heterotrophic, meaning they cannot produce their own food, unlike plants. Plants are able to perform photosynthesis to obtain their energy by converting carbon dioxide and water into oxygen and glucose. However, unlike animals who go out to either hunt or forage food (for example, a deer eating grass or a wolf hunting a bunny), fungi absorb nutrients from dead or living organisms. For example, a fungi might be seen next to a decaying oak log. Or, it might be seen on the bark of a living tree.

Small, nonpolar hydrophobic molecules such as fatty acids
a. pass readily through a
membrane's lipid bilayer
b. diffuse very slowly through the lipid bilayer
c require special channels to enter a cell
d. are actively transported across cell membranes
c. must enter the cell via endocytosis
Answers
Answer:
a. pass readily through a membrane's lipid bilayer
Explanation:
Small, nonpolar hydrophobic molecules such as fatty acids pass readily through a membrane's lipid bilayer.
Small, nonpolar hydrophobic molecules such as fatty acids pass readily through a membrane's lipid bilayer. Therefore, the correct option is option A.
The hydrophilic (water-loving) heads of the two layers of phospholipids in the lipid bilayer face outward towards the aquatic surroundings, while the hydrophobic (water-hating) tails point inward towards one another. The hydrophobic tails of phospholipids share characteristics with nonpolar hydrophobic compounds like fatty acids. These tiny molecules can easily dissolve in the hydrophobic area of the lipid bilayer because of their hydrophobic nature.
Therefore, the correct option is option A.
