X-linked recessive traits are more common in males because the decease is only carried on the X chromosome therefore females need two copies of the gene to have the decease whereas in males they only need one copy. This is because males are XY and females are XX
X-linked recessive traits are more common in males than females because males only have one X chromosome while females have two. This means that if a male inherits an X chromosome with a recessive allele, it will be expressed in his phenotype.

Which organism exhibits behavioral adaptation?
- an owl with large pupils and eyes that enable it to see better at night.
- A possum playing dead to increase its chances of survival.
- An insect that mimics it’s environment to hide from its predators.
- A desert plant that sheds its leaves to lessen water loss during the dry season.
Answer:
B
Explanation:
a possum playing dead to increase its chances of survival
All of the options provided involve some form of adaptation, but the one that specifically involves behavior is the possum playing dead to increase its chances of survival. Hence option B is correct.
What is Behavioral adaptation?Behavioral adaptation refers to changes in an organism's behavior that help it to better survive and thrive in its environment. Playing dead, or "playing possum," is a behavioral adaptation that some animals, including possums, use when they feel threatened.
By playing dead, the possum is essentially trying to fool its predator into thinking that it is no longer a threat or a viable prey item. This behavior can increase the possum's chances of survival by deterring predators and allowing it to escape unharmed.
Other examples of behavioral adaptation include migration, hibernation, and communication between members of the same species. These behaviors can help organisms conserve energy, avoid harsh environmental conditions, and increase their chances of finding a mate or resources for survival.
Hence option B, A possum playing dead to increase its chances of survival is correct.

How can a hormone that is present in very small quantities within the bloodstream elicit such a large response within a cell?.
Answer:
-Cells degrade the hormone into many tiny molecules, and then each piece creates a response within the cell.
Explanation:
Apply your understanding of how living organisms use energy to argue in favor of why it is either beneficial or detrimental for cells to use ATP rather than directly using the energy stored in the bonds of carbohydrates to power cellular reactions.
a. ATP is readily available in the form of a single unit that provides a consistent, appropriate amount of energy. If cells harvested energy from various carbohydrate compounds, they would need to tailor each reaction to each energy source.
b. ATP energy cannot activate the ROS dependent stress response whereas food molecules are responsible for activating ROS.
c. ATP is low in energy, but food molecules (in the form of carbohydrates) possess higher levels of energy that cells can use.
d. ATP is readily available to cells, unlike the carbohydrate compounds that have to first be phosphorylated in order to release their energy.
Answer:
ATP is readily available in the form of a single unit that provides a consistent, appropriate amount of energy. The cell would need to tailor each reaction to each energy source if it harvested energy from different compounds.

How many reactions needing light occur during photosynthesis?
Answer:
Explanation:
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.

Describe the structure of DNA and the possible base pairs it contains.
DNA is a molecule made up of thousands of atoms and is very long and thin. It is made up of two twisted chains or "backbones." A double helix is the term for this structure. It would appear like a ladder if you could straighten a DNA molecule out. The ladder's "rungs" are built up of two smaller molecules called bases.
adenine (A) and thymine (T) join together = A-T
guanine (G) and cytosine (C) join together = G–C
DNA is a molecule with a double helix structure. This means that it is shaped like a twisted ladder. The backbone of the molecule is made up of two long chains that spiral around each other. The struts of the ladder are base pairs, which are made up of two bases joined together.
There are four bases: adenine (A), cytosine (C), guanine (G) and thymine (T). These can only join together to form two possible base pairs: adenine–thymine or cytosine–guanine.
1) The chart indicates the digestion and nutrient absorption for two different species of animals.
Which of these describes the interaction between the food intake and nutrient absorption for these two different species?
A) Carnivores have a more efficient intestinal absorption since meat is higher in caloric value.
B) Carnivores have more digestive organs over which food digestion and nutrient absorption can occur.
Herbivores require a shorter digestion time with a higher amount of nutrient absorption into the bloodstream.
D) Herbivores have a greater intestinal length that allows for increased absorption of nutrients from a plant-based diet.
Herbivores having a greater intestinal length that allows for increased absorption of nutrients from a plant-based diet best describes the chart.
What are Herbivores?These are organisms which feed on plants and are referred to as primary consumers.
They possess four stomachs and a greater intestinal length that allows for increased absorption of nutrients from plant diet which contains polysaccharides such as cellulose.

Several models of atoms are mentioned in this lesson. Plum pudding, planetary and quantum mechanical. Which reason below explains why there are different atom models?
Because atoms have changed their structure over time
Because there are different types of atoms
Because the ideas about the models changed as more discoveries were made about the atom
Because many people came up with models at the same time
Answer:
Because the ideas about the models changed as more discoveries were made about the atom
Explanation:
The structure of the atom was not always known and it took many discoveries to fully figure it out. Through these discoveries, many models were proven invalid; though they still helped in the long run by providing a basic idea on the basis of an atom.
Remember, models are able to change over time, they are merely theories after all; and scientific theories change, unlike laws.
what is locomotion? how does it happen?
Answer:
Locomotion is basically the ability to move from one point to another point. It happens through our skeletal system and our muscular system working together.
Explanation:
Locomotion is the ability to move from one point to another. Locomotion is in any living organism that can move from one place to another, things like the ability to walk/run/climb/crawl any way to move to one place to another is locomotion. To describe how locomotion works I will use the example of a human, humans have a skeleton system and attached to those bones are tendons which are a part of the muscular system, the skeletal and the muscular system work together to give humans the ability to move, same case in most living organisms.

The food chain and food web serve as conduits for the energy flow. Plants, who are the primary energy producers in an ecosystem.
What is the mechanism of energy flow in an ecosystem?The autotrophs that absorb energy from the sun are an excellent example of how energy moves through an ecosystem.
Utilize their chloroplasts to accumulate sunlight, which is then partially altered into chemical energy during photosynthesis.
Herbivores eat the autotrophs thereafter, converting the plant's energy into fuel for themselves. Then, carnivores consume the herbivores, followed by other carnivores consuming the carnivores.
Therefore, energy flow in an ecosystem is connected by different trophic level.
