When the
When the moon casts its shadow on Earth, a lunar eclipse occurs.
The last option is correct.
How do we explain?A lunar eclipse happens when the Earth's shadow falls on the moon. This can only happen during a full moon, when the sun, Earth, and moon are perfectly aligned.
The Earth's shadow has two parts: the umbra and the penumbra. The umbra is the darkest part of the shadow, and it is where the moon will completely disappear. The penumbra is the lighter part of the shadow, and it is where the moon will only partially disappear.
Therefore, the last option is correct.

The Hardy-Weinberg equation shows the frequencies of 100 percent of the alleles for a specific gene in a population.
If biologists can show that either p or q is changing over a period of time, what is occurring in the population?
The population is evolving.
The population is decreasing in size.
The population is stabilizing.
The population is not evolving.
Answer: I believe that the answer is that the population is evolving
Explanation: I hope that this helps
In Hardy-Weinberg equation, If biologists can show that either p or q is changing over a period of time, the population is decreasing in size.
What do you mean by Hardy-Weinberg equilibrium?The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation.
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
For populations in the Hardy-Weinberg equilibrium, the equation connects allele frequencies to genotype frequencies. This equation allows us to compare a population's genetic structure in reality over time to the expected genetic structure.

Dopamine, Acetylcholine, Serotonin
Explanation:
Answer:
One common neurotransmitter is dopamine. It is an excitatory neurotransmitter that is involved in movement, learning, attention, and emotion. GABA is another common neurotransmitter, and it is a major inhibitory neurotransmitter. It is involved in anxiety, arousal, and sleep. Glutamate is a major excitatory neurotransmitter, and it is involved in learning and memory.
Acetylcholine: Serves as a messenger between each motor neuron and skeletal muscles, which accounts for its role in helping to control skeletal muscles.
Serotonin: Affects sleep, hunger, mood, and arousal; connected to aggression and abnormal behavior
Norepinephrine: Helps control arousal and alertness; helps in regulating mood

Why do elderly persons often develop bowed back and appear to lose height?
Answer:
When we get older, we experience a loss of bone density and our bones begin to thin and become weaker, which results in osteoporosis, causing us to develop bowed backs and appear to lose height.
We lose bone density as we age, and our bones start to thin and weaken. This leads to osteoporosis, which makes us appear smaller and causes us to acquire bowed backs.
What is osteoporosis ?Osteoarthritis is an osseous disease that arises when the body makes either too little bone or loses too much bone. Like a result, bones deteriorate and are more prone to breaking from a trip or, in extreme circumstances, from tiny bumps or sneezes. Under a magnification, healthy bone resembles a honeycomb; the term "osteoporosis" refers to porous bone.
What is treatment of osteoporosis?Typically, bisphosphonates are used initially for treating osteoporosis. Among these is the when first tablet Alendronate (Fosamax). Weekly or monthly pills of was also (Actonel). Ibandronate (Boniva), a tablet taken every month or an IV infusion given every 3 years. The most accurate test for identifying osteoporosis and determining the risk of fracture is commonly believed to be bone density testing by DXA now at hip and spine. Some persons get peripheral DXAs, which assess the thumb and heel bone densities.

A. Gorillas recently evolved from humans.
B. They have no common ancestors.
C. They probably have
recent common ancestor.
O D. They are probably the same species.
SUBMIT
Answer:
they probably have a recent common ancestor
Explanation:
They probably have recent common ancestor. Therefore, option (C) is correct.
What is evolution?Evolution is the process by which species change over time, usually through natural selection. The theory of evolution is supported by a vast body of evidence from many fields, including genetics, paleontology, and comparative anatomy.
Evolution occurs because of changes in the genetic code of organisms, which can be caused by mutations, gene flow, genetic drift, and natural selection. Over time, these changes can accumulate and result in the development of new species from ancestral forms. Evolution is a slow process that occurs over many generations, and it has been responsible for the incredible diversity of life on Earth, from the simplest bacteria to the most complex animals and plants.
The fact that humans and gorillas have one different amino acid in their hemoglobin sequence suggests that they have a recent common ancestor. This is because the hemoglobin protein plays an essential role in carrying oxygen in the blood and is highly conserved across species that share a common ancestor.

Describe what would happen to the abiotic factors within the ecosystem if the bacteria were eradicated from the ecosystem.
Answer: If a abiotic factor was to be removed from the ecosystem it can affect the entire ecosystem and all of the organisms that live there
Explanation:
Abiotic means which does not have life for example air, water, soil. Absence of bacteria can influence the abiotic factors in adverse ways.
What are abiotic factors?Abiotic components plays a major role in ecosystem, while biotic components are dependent on abiotic factors for their survival.
Both abiotic and biotic factors are related to each other, if any of these factors changes, it will adversely affect the ecosystem.
For instance, if bacteria were eradicated from ecosystem, it will affect the functioning of abiotic components which can result in increased pH, decreased decomposition etc.

The picture shows a contractile vacuole of a unicellular freshwater organism. The contractile vacuole regulates the flow of water into and out of the cell in an aquatic environement. What condtions cause the contracile vacuole to fill with water? Your answer: The concentration of water is greater outside the cell than inside the cell. The concentration of water inside the cell is the same as the concentration outside the cell. The temperature of water in the vacuole is higher than the temperature of its environment.
Answer:
The concentration of water is greater outside the cell than inside the cell.
Explanation:
In living cells, water moves by Osmosis across the cell membrane, which acts as the semi-permeable membrane. Osmosis is the movement of water molecules from a region of high water concentration (low solute concentration) to a region of low water concentration (high solute concentration).
The contractile vacuole of this freshwater organism helps regulate water intake and exit by storing excess water. According to osmotic flow, water will flow into the organism via its cell membrane (semi-permeable membrane) because the concentration of water outside the cell is high than inside the cell, hence, this causes an osmotic gradient causing water to flow into the cell. The water that flows into the cell is stored in the Contractile vacuole.

Kangaroos are mammals that lack a placenta. Therefore, they must have an alternate way of supplying the developing embryo with
Answer: yolk sac
explanation:
the placenta does not develop for a long time so the alternate way of supplying the developing embryo is through the yolk sac which the embryo can receive nutrients and respiratory gas exchange through which the placenta will be formed later.
Kangaroos are mammals that lack a placenta; therefore, they must have an alternate way of supplying the developing embryo with nutrients, as these should be passed from the mother to the embryo during the time of pregnancy.
What is the function of the placenta in pregnancy?The placenta is an organ that develops during pregnancy to provide nourishment to the growing fetus and to remove waste products from the baby's blood and is attached to the wall of the uterus and connected to the baby by the umbilical cord, it is responsible for producing hormones that maintain the pregnancy, such as progesterone, which helps to keep the lining of the uterus thick, also produces human placental lactogen, which helps stimulate the mother's mammary glands to produce milk.
