There are a number of organelles that are exclusively or mostly found in plant cells. The organelles in which photosynthesis occurs are called chloroplasts. Green pigment chlorophyll, which is present in chloroplasts, enables them to absorb light energy and transform it into chemical energy.
Cell wall- The hard cell wall that surrounds plant cells is constructed from cellulose, hemicellulose, and other polysaccharides.
Huge central vacuole- The majority of the space inside plant cells is taken up by a large central vacuole. Water, nutrients, and waste materials are present in the vacuole, which also contributes to the regulation of the internal environment of the cell.
The interchange of tiny molecules like ions and carbohydrates between neighboring plant cells is made possible by a structure called a plasmodesmata, which connects the cells.
Starch grains- Plant cells frequently store extra glucose in starch grains, which may be digested when needed to provide energy.

in appositional growth, chondrocytes within cartilage divide and secrete new matrix. true/flase
Answer: FALSE
Explanation:
in appositional growth, chondrocytes within cartilage divide and secrete new matrix.
True. In appositional growth, chondrocytes within cartilage divide and secrete new matrix.
In appositional growth, chondrocytes (cartilage cells) within the cartilage tissue divide and secrete new matrix to the outside of the existing cartilage, resulting in an increase in the size of the tissue. This type of growth allows for the expansion of cartilage in width or thickness, as opposed to interstitial growth, which is the growth of cartilage from within by cell division and matrix production.
Throughout the course of appositional growth, chondrocytes in the perichondrium, the cartilage's outer layer, divide and secrete a new matrix on the cartilage's surface. For the development and maintenance of bones, joints, and other tissues that depend on cartilage for support and mobility, this process results in an increase in cartilage thickness.
Other tissues, including bone, can also experience appositional development, which helps with bone remodeling and healing. On the surface of the existing bone tissue, the process in bone involves the activity of osteoblasts, cells in charge of forming a new bone matrix.

lymphatic organs that filter lymph before it reenters the blood are called?
Lymphatic organs that filter lymph before it reenters the blood is called “filters of the lymph".
By eliminating waste and pathogens from the lymph, lymph nodes act as "filters of the lymph". The lymphatic capillaries absorb any pathogens in the interstitial fluid and carry them to a neighboring lymph node. Many pathogens that pass through this organ are internalized and killed by dendritic cells and macrophages, which then eliminate them from the body. T lymphocytes, B cells, and accessory cells of the adaptive immune system also mediate immunological responses at the lymph node. The bean-shaped lymph nodes are encased in a robust connective tissue capsule that is divided into compartments by trabeculae, just like the thymus.

Bacteria comes in different shapes. How can this be used to identify the source of an infection
The shape of a bacterium can provide important clues about the source of an infection. Different bacterial species have distinct shapes, which can help identify them and pinpoint the source of the infection. The size and arrangement of the bacteria can also be used to help identify them.
By examining the shape and size of the bacteria causing an infection, medical professionals can sometimes determine the type of bacteria involved and the most appropriate treatment. For example, certain antibiotics may be more effective against gram-positive cocci (spherical bacteria that have a thick peptidoglycan cell wall) than against gram-negative bacilli (rod-shaped bacteria that have a thinner peptidoglycan cell wall as well as an outer membrane).
Additionally, knowing the shape of the bacteria can sometimes help identify the source of the infection, such as whether it came from contaminated food, water, or a person's own microbiota.
It is important to note that identifying the source of an infection based on the shape of the bacteria is just one aspect of a comprehensive diagnosis. Other factors, such as the symptoms, location of the infection, and results of diagnostic tests, must also be taken into account to determine the most effective treatment.

a human karyotype indicates the sex chromosomes of an individual to be xyy. how many barr bodies would be visible in the nuclei of somatic cells from this person
In the nuclei of somatic cells from an individual with XYY karyotype, no Barr bodies would be visible.
In the case of an individual with an XYY karyotype, this indicates that they have two Y chromosomes and one X chromosome. This condition is known as XYY syndrome or Jacob's syndrome. Barr bodies are the condensed, inactive X chromosome in female somatic cells. Since males have only one X chromosome, they do not form Barr bodies.
In normal female cells, one of the two X chromosomes is randomly inactivated to form a compact structure called a Barr body. This process is called X-inactivation, and it balances the expression of genes between males and females. In males, the single X chromosome is not inactivated, and therefore no Barr bodies are present in the nuclei of their somatic cells.
In the case of an individual with an XYY karyotype, they still only have one X chromosome, and therefore, they would not have any Barr bodies visible in their somatic cells. This is because only females have the X-inactivation process, and males do not. In this case, since XYY syndrome only affects males, there would be no need for any Barr bodies to be present in their somatic cells.

A roller-coaster is at the top of a 62-meter hill. The car and its passengers have a total mass of 1,088 kilograms. By the time the car reaches the bottom of the hill, its speed is 74 miles per hour (33 meters per second). How much kinetic energy does the car have at the bottom of the hill?
KE=12mv2
2,978,944 J
1,184,832 J
17,952 J
592,416 J
Answer:
The car has a kinetic energy of 592,416 J at the bottom of the hill.
Explanation:
The formula for kinetic energy is KE = 0.5 * m * v^2, where m is the mass and v is the velocity. So to find the car's kinetic energy at the bottom of the hill, we need to convert the rate from miles per hour to meters per second.
74 miles per hour = 33.5 meters per second
Now, we can plug in the mass and velocity into the formula:
KE = 0.5 * 1088 kg * 33.5^2 m/s^2
KE = 0.5 * 1088 * 1128.25 m^2/s^2
KE = 592,416 J
So, the car has a kinetic energy of 592,416 J at the bottom of the hill.
