What statement is true about cell walls.
1
Cell walls are present in animal cells
O All cells have cell walls
O Cell walls support, shape, and protection the cell
O In plants, cell walls are made of proteins
Answers
Answer:
Although 3 and 4 are great answers, I honestly think the answer is C. Because you can simply define the cell wall as a semi-rigid thick protective structure that surrounds the cell membrane of some types of cells for protection and defining the shape of the cell. The cell membrane alone cannot provide the required rigidity or strength. All living organisms are composed of cells. Cell walls contain only little amount of protein in the cell wall.
Explanation:
Not all cells have a cell wall; the cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell. Cell walls are found in both prokaryotes and eukaryotes, although not all cells have cell walls. Animal cells does not have a cell wall; Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not. Chloroplasts enable plants to perform photosynthesis to make food.
Onepage review on why understanding gas and vapors in a work setting is important and what we can do in our workplace to prevent accidents with gases and vapors.
Answers
Understanding gas and vapours in a work setting is incredibly important for workplace safety. Gas and vapours can contain noxious substances that, if exposed to, can lead to serious injury or health implications.
In order to prevent such accidents, employers must perform risk assessments in order to assess and identify any areas of risk and put in place control measures to limit them. If gas and vapours are used onsite, then suitable ventilation and extraction systems should be in place.
Employers should also ensure that their staff are aware of the potential risks associated with such substances and provide adequate training and instruction in how to work safely. Finally, employers should also check that any necessary personal protective equipment is provided and communications are in place to be able to notify relevant emergancy responders in case of an accident.

Answer:
As you move away from the Earth, the pull of Earth's gravity weakens. ... The bigger the object, the stronger the force of gravity it exerts.
Answer:
This force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers. This means that as you move away from an object the gravitational force decreases.

here are two wolves that have the same proteins for paw size in their cells. The wolves have different parents. What can you say about the wolves' paw size
Answers
The paw size of the two wolves with the same proteins for paw size in their cells and different parents is likely to be similar.
The proteins in their cells are responsible for determining their paw size, and since they have the same proteins, it can be inferred that their paw size will also be similar, despite having different parents. If the two wolves have the same proteins for paw size in their cells and have different parents, it suggests that there may be a genetic trait for paw size that is being passed down through multiple generations. However, other factors such as environmental influences may also play a role in determining the actual size of the wolves' paws.

Which statement is FALSE about epigenetic modifications?
a. The tails of the nucleosome octamer components can be modified with methylation
b. The tails of the nucleosome octamer components can be modified with acetylation
c. Only non-DNA components of chromatin are modified with epigenetic markers
d. Epigenetic modifications control whether a region is euchromatin or heterochromatin
Answers
The false statement about epigenetic modifications is:
c. Only non-DNA components of chromatin are modified with epigenetic markers.
Epigenetic modifications refer to changes in gene expression that do not involve changes to the underlying DNA sequence. These modifications can be inherited and can influence how genes are turned on or off in different cells or at different stages of development.
a. The tails of the nucleosome octamer components can be modified with methylation: This statement is true. Methylation of the tails of nucleosome octamer components, which are made up of histone proteins, can affect gene expression by either activating or repressing the associated genes.
b. The tails of the nucleosome octamer components can be modified with acetylation: This statement is also true. Acetylation of histone tails is another type of epigenetic modification that can influence gene expression. Acetylation generally leads to gene activation by relaxing the chromatin structure and allowing transcription factors to access the DNA.
d. Epigenetic modifications control whether a region is euchromatin or heterochromatin: This statement is true. Epigenetic modifications play a crucial role in determining whether a region of DNA is in a euchromatin state, which is more accessible for gene expression, or a heterochromatin state, which is more condensed and less accessible for gene expression.
In summary, the false statement is c. Only non-DNA components of chromatin are modified with epigenetic markers. Epigenetic modifications can occur on both DNA and non-DNA components of chromatin, such as histone proteins. These modifications can have significant impacts on gene expression and are essential for cellular development and function.

Gene expression patterns can be used to test hypotheses based on morphology. For example, the regulatory gene Bapx1 is expressed in the hinge of the developing lower jaw in fishes and reptiles. Where would you predict Bapx1 expression to occur in mammals?
A. in the developing cheekbone
B. in the developing lower jaw
C. in the mature lower jaw
D. in the developing ear bones
Answers
Answer:
The correct answer is option D. "in the developing ear bones".
Explanation:
The developing lower jaw of fishes and reptiles has a variety of bones that are joined together, forming the mandible that they use to eat their preys. Some bones in the developing lower jaw of fishes and reptiles are equivalent to the developing ear bones of mammals. Therefore we can predict that the Bapx1 expression in mammals will occur in the developing ear bones. About this evolutionary relationship, scientist Zhe-Xi Luo of the Carnegie Museum of Natural History in Pittsburgh states "Reptiles have [a] jaw full of ear bones from mammals and mammals have an ear full of jawbones of reptiles".
specialized cells of the dermal system in plants that function in gas exchange are called
Answers
Specialized cells of the dermal system in plants that function in gas exchange are called stomata.
The little apertures known as stomata are found on the epidermis of leaves. Stomata are visible under a light microscope. Stomata can be found on the stems and other portions of various plants. In gaseous exchange and photosynthesis, stomata are crucial. Through opening and closing, they regulate the rate of transpiration.
The stomata are made up of tiny pores termed stoma that are encircled by two guard cells. The turgidity of guard cells determines how frequently stomata open and close. The pore's surrounding cell wall is resilient and adaptable. Both monocots and dicots typically have different guard cell shapes, but the mechanism is the same in both. Guard cells have chloroplasts and are shaped like beans. They absorb light and have chlorophyll in them.
Hence, stomata cell plays role in gaseous exchange.

what role do the kidneys play in the raas and bnp system?
Answers
The kidneys play a crucial role in both the RAAS (renin-angiotensin-aldosterone system) and BNP (brain natriuretic peptide) systems. In the RAAS system, the kidneys release renin in response to low blood pressure, which then converts angiotensinogen to angiotensin I.
Angiotensin I is then converted to angiotensin II by the angiotensin-converting enzyme (ACE) in the lungs. Angiotensin II causes vasoconstriction and the release of aldosterone, which helps to retain sodium and water to increase blood pressure. In the BNP system, the kidneys release the hormone BNP in response to high blood pressure and volume. BNP causes vasodilation and promotes the excretion of sodium and water to decrease blood pressure.
Therefore, the kidneys are a crucial organ in regulating blood pressure through both the RAAS and BNP systems.
The kidneys play a crucial role in the RAAS (Renin-Angiotensin-Aldosterone System) and BNP (B-type Natriuretic Peptide) systems. In the RAAS system, kidneys help regulate blood pressure and fluid balance by releasing the enzyme renin, which initiates a cascade of reactions leading to the production of aldosterone. Aldosterone, in turn, helps retain sodium and water, ultimately increasing blood pressure when needed.
In the BNP system, the kidneys assist in regulating blood pressure and fluid balance by responding to BNP released by the heart. BNP acts as a diuretic, promoting sodium and water excretion by the kidneys, which reduces blood volume and lowers blood pressure.
In summary, the kidneys play a vital role in maintaining blood pressure and fluid balance through their involvement in both the RAAS and BNP systems.
