What events contribute to genetic drift in the Florida panther
Answers
At the time, the Florida population was reported to be down to 30 animals, with so much inbreeding that most of the panthers were linked to each other. This has resulted in genetic issues such as poor sperm counts and improperly formed testicles, resulting in limited reproductive success.
What is the most significant cause contributing to the fall of the Florida panther population?A team of geneticists and conservation biologists determined in 1992 that the Florida panther will become extinct in 24-63 years owing to its tiny population size, and related genetic health concerns caused by inbreeding.
The introduction of additional panthers into the Florida panther population assisted in reversing the consequences of inbreeding by introducing new gene versions that concealed the detrimental effects of the recessive gene versions already existing in the Florida panther population.
The most serious dangers to Florida panthers are habitat loss, fragmentation, and degradation

Which brain imaging techniques allow for the observation of structure but do not allow observation of brain activity?
Answers
With the use of cutting-edge noninvasive neuroimaging methods like EEG and fMRI, researchers may now watch brain activity while volunteers carry out different perceptual, motor, and/or cognitive tasks.
Which three methods enable the study of the active brain?There are several ways to go about gathering data about the anatomy and activities of the brain. Functional magnetic resonance imaging (fMRI), magnetoencephalography (MEG), and electroencephalography are the three most popular and often utilised measurements (EEG)
Why is fMRI employed?It can be used to investigate the functional architecture of the brain, identify the regions of the brain responsible for vital functions, assess the consequences of a stroke or other illness, or determine how best to treat the brain. Other imaging methods may be unable to find abnormalities in the brain that fMRI can.

Contain proteins that carry out oxidative metabolism, a process whereby energy is extracted from macromolecules and converted to atp.
Answers
identify what happens to light in this model of the greenhouse effect
Answers
This process begins with the arrival of radiation from the Sun to the Earth's surface, where most of the energy is received as ultraviolet radiation. Of this energy, part is absorbed by the atmosphere (ultraviolet radiation), another part is reflected by clouds, and another reaches the planet's surface (as visible light) by heating it. Once this radiation has reached and warmed the Earth's surface, the Earth returns this energy in the form of infrared radiation (thermal energy) and is reflected and sent back to the atmosphere and space.
It should be noted that thanks to this process the temperature of the planet is compatible with life as we know it. However, pollution activities due to the fossil burning fuels and deforestation by humans have intensified the effects of this phenomenon, being the main cause of global warming.

How do plants get the nitrogen they need to grow?
OA. They absorb nitrogen through their roots.
OB. They absorb nitrogen gas from the atmosphere.
OC. They create it during photosynthesis.
OD. They create it during respiration.
SUB
Answers
Answer:
They absorb nitrogen through their roots.
Explanation:
Nitrogen is ain't formed or involved in photosynthesis and respiration. So these options are eliminated.
Next is atmosphere. We know the [tex]\%[/tex] composition of nitrogen in the atmosphere is pretty high but plants are not capable of absorbing these free nitrogen directly from the atmosphere.
Hence plants absorb nitrogen from the soil in the form of ions like ammonium ions, nitrate ions, nitrite ions. Some plants also have leguminous nodules where tiny bacterias like rhizobium live and helps in the process of nitrogen fixation.

Photosynthetic algae live within the tissues of the organisms that build coral reefs. The coral organisms provide the algae with carbon dioxide for photosynthesis. The algae supply the corals with oxygen, sugar, and amino acids. Which statement best summarizes the sources of energy in the relationship between algae and coral?
Answers
The coral organisms provide the algae with carbon dioxide for photosynthesis.
How does coral get energy from algae?Algae inhabit coral polyps and use sunlight to produce sugar, which they use as fuel. The polyp receives this energy, which supplies it with much-needed nutrition. In exchange, coral polyps give algae carbon dioxide and a safe place to live. Additionally, corals consume zooplankton, which are minuscule floating organisms.
What are the corals source of energy?The ecosystem of coral reefs is made up of a variety of species that interact with one another and the surrounding environment. The ecosystem's primary source of energy is the sun. Photosynthesis is the process by which phytoplankton, algae, and other plants transform light energy into chemical energy.

Lack of exercise is a determinant for many chronic disease, such as cardiovascuolar disease. what is one direct contributing factor to lack of exercise?
Answers
Lack of exercise causes a variety of health issues, from weight gain that initially seems harmless to cardiovascular disorders and a significantly increased risk of having a stroke.
Fat accumulation in arteries and blood vessels that obstruct the flow of blood to the heart is the primary cause of cardiac disorders.
Exercise increases the function of the same arteries after a high-fat meal compared to before, and it also reverses the arterial dysfunction brought on by fatty foods.When the human body runs out of energy during exercise, it turns to stored saturated fat in our bodies to provide additional energy. This demonstrates that regular exercise is preferable to inactivity for lowering saturated fats, type 2 diabetes risk, and chronic heart disease risk.
Perhaps obesity, which prevents a person from engaging in many physical activities, is the one element contributing to a lack of exercise.
Thus, we can infer that fat accumulation occurs from inactivity, which can cause cardiac ailments as well as chronic illnesses. Since it is difficult for obese people to participate in any physical activity, obesity is a significant contributing factor to the lack of exercise among people.

Which cell structure is responsible for making ribosomes? And where is it located?
Answers
The production and assembly of the cell's ribosomes takes place in the nucleolus, a spherical component of the cell's nucleus. Ribosomes can be seen connected to the endoplasmic reticulum or floating in the cytoplasm.
The cytoplasm of the cell contains ribosomes "freely," and they are also affixed to the rough endoplasmic reticulum. The cell nucleus provides information to ribosomes, and the cytoplasm provides building blocks. The biological machinery that produces proteins is known as a ribosome. Each cell contains several ribosomes, which are each composed of two subunits. As they move along the messenger RNA molecule's length, these two subunits read each three-letter codon after locking around the messenger RNA. Ribosomes are produced in the cytoplasm of bacterial cells by the transcription of several ribosome gene operons. In eukaryotes, the process occurs both in the cytoplasm of the cell and in the nucleolus, a section of the cell nucleus.
