Answer:

The correct answer would be -

A. diatoms

B. Toxoplasma gondii

C. Giardia lamblia

D. Pelomyxa

E. Rhodophyta - Corralinna

F. foraminiferan

G. euglena

Explanation:

1. Protist A

The given characteristics of this protist are similar to the diatoms as diatoms are the protists that are covered with silica-made glassy shells with photosynthetic pigment and the sperm is known to have flagella. found in marine water normally.

2. protists B

Toxoplasma gondii is a parasitic protist that is found in cat feces and homology with Giardia intestinalis and causes GI tract irritation or distress in humans. This parasitic protist have flagella and two nuclei in the cell.

3. protist C

Giardia lamblia is known to have two nuclei and perform conjugation and shows homology with dinoflagellates and apicomplexans. it is known to be present in the feces of the goat covered with cilia.

4. Protist D

Pelomyxa is found in moist soil and has an amoeba-like movement with web-like morphology. it is mold similar to Dictyostelium.

5. Protist E

Corralinna is a Rhodophyta it shows association with the coral reef, has no flagella and contains photosynthetic pigments. It is used in sushi making and is harvested largely for this purpose.

6. Protist F

Foraminiferan shows homology to Pyrgo anomala, which contributes to chalk- and limestone-forming sediments as it has a shell of calcium carbonate found in marine water with small pores on the shell from which the pseudopodia comes out.

7. Protist G

euglena found in freshwater and tends to swim towards the light. Euglena has no cell wall but the membrane has pellicle in it.

Explanation:

1) These are responsible for the transportation of blood from the heart to all parts of the body. These vessels collect blood through capillaries and transport it towards the heart. These vessels connect arteries and veins.

2. All arteries carry oxygenated blood except pulmonary arteries which carry deoxygenated blood. All veins carry deoxygenated blood except pulmonary veins which carry oxygenated blood. These carry mixed oxygenated and deoxygenated blood.

3. Arteries have no valves in them except at the base of the pulmonary trunk and aorta. Valves are present in veins. These valves prevent the backflow of blood. There are no valves in them.

4. Arteries have high blood pressure. Veins have low blood pressure. There is falling pressure in them.

5. In arteries, waves of blood pressure or pulse due to heartbeat can be detected. There is no pulse. There is no pulse.

6. Blood flows rapidly between 400-500mm per second in the aorta and decreasing in arteries and arterioles. The rate of blood flow increases from smaller to larger veins. Blood flow is slowest which is less than 1mm per second.

7. Arteries have a smaller bore and thick walls. Veins have a larger bore and thin walls. Capillaries have a larger bore and the wall is of one cell in thickness.

8. There are thick muscle layers and elastic fibers present. The elasticity helps to change the pulsating flow of blood. There are thin muscle layer and less elastic fibers present in veins. So, they are less elastic. No muscles or elastic fibers are present.

9. There is no exchange of materials. There is no exchange of materials. These are responsible for the exchange of gases and nutrients.

Explanation:

Truly, the typical X shaped chromosomes is the result of DNA replication. When the DNA has replicated, it then condenses and coil into the X-shaped of the chromosome. This then implies that replicated chromosomes take the X-shaped structures seen under a microscope.

When this replication occurs, the chromosome is made of two structures that are identical. They are known as the sister chromatids. These chromatids are actually joined at the centromere.

Explanation:

Antibiotics are added to the animal feed or drinking water of cattle, hogs, poultry and other food-producing animals to help them gain weight faster or use less food to gain weight.

Because all uses of antimicrobial drugs, animals contribute to the development of antimicrobial resistance, it is important to use these drugs only when medically necessary.

the production (e.g. growth enhancement) purposes as well as for the treatment, control or prevention of animal diseases. Even today, it is not entirely understood how these drugs make animals grow faster. The drugs are primarily added to feed, although they are sometimes added to the animals’ drinking water.

Answer:

The new modification in Organism B is the tail.

Explanation:

This might indicate that the organism has to sprint in order to catch prey or to get away from predators. The organism is most likely not a prey, since it has sharp teeth, making it a carnivore. The tail helps in stabilizing the animal while running. The animal might have new threats that have developed over the years (like humans).

Answer:

C. Oxygen was introduced into the environment allowing for many other organisms to survive

Explanation:

A is not correct because that is the opposite of what photogenic organisms do.

B is not correct because ATP and glucose do not apply.

D is not correct because photosynthesis does not have a direct affect on the water cycle itself.

Answer:

3.5 cm

Explanation:

Mass of mercury = 3.380

Diameter = 0.200

At t = 0 and 25 degrees we have 13.596 and 13.543 as density

At 0 degree = v = 3.380/13.596 = 0.2485

At 25 degrees = 3.380/13.534 = 0.2497

We use volume of cylinder to get height

At 0⁰ height = 7.91

At 25⁰ = 7.944

The difference in height = 0.035

Multiply by 100 = 0.35 x100

= 3.5cm

Complete question:

Homogenization of rat liver cells results in the rupture of the cell membranes. Centrifugation of this homogenate compacts some of the homogenates into a pellet at the bottom of the centrifuge tube. Bathing this pellet with a solution containing succinate (a four-carbon organic compound), phosphate ions, oxygen, and ADP yields metabolic activity, including the production of ATP and the uptake of oxygen. This pellet most likely contains

1. peroxisomes

2. mitochondria

3. lysosome

4. Golgi complex

5. endoplasmic reticulum

Answer:

2. Mitochondria

Explanation:

Mitochondria are one of the biggest organelles in the cell. They degrade organic molecules, releasing chemical energy from their bindings through a process that consumes oxygen: cellular respiration.

The released energy is stored as ATP through the cellular respiration process and then is used in other cellular activities.

Mitochondria are more grouped in areas or tissues with higher energetical requirements.

As cellular respiration characterizes by consuming oxygen and producing ATP, we can assume that the pellet mostly contains mitochondria.

By considering the components of the pellet, we can deduce that it most likely contains MITOCHONDRIA.

Cellular respiration is a series of reactions by which aerobic cells consume oxygen and nutrients (e.g. glucose) to produce ATP and carbon dioxide.

Cellular respiration has three sequential steps: glycolysis, the Krebs cycle and oxidative phosphorylation.

Mitochondria are the energy center of the eukaryotic cells. The Krebs cycle and oxidative phosphorylation occur in the mitochondria, while glycolysis occurs in the cytoplasm.

The Krebs cycle produces a four-carbon molecule known as succinate.

Adenosine triphosphate (ATP), the energy coin of the cell, is produced from ADP and phosphate (Pi) in the three stages of cellular respiration.

Finally, oxygen is consumed during oxidative phosphorylation.

In conclusion, by considering the components of the pellet, we can deduce that it most likely contains MITOCHONDRIA.

The graph looks something like this (though not exactly. It just has the same sort of shape.)

Answer:

Fats are actually a type of lipid. Lipids are a major class of biochemical compounds that includes oils as well as fats. Organisms use lipids to store energy and for many other uses.

Lipid molecules consist mainly of repeating units called fatty acids. There are two types of fatty acids: saturated fatty acids and unsaturated fatty acids. Both types consist mainly of simple chains of carbon atoms bonded to one another and to hydrogen atoms. The two types of fatty acids differ in how many hydrogen atoms they contain.

Explanation:

Can I plz have brainliest

The shape of the types of fatty acid molecules has an impact on their solidification.

It should be noted that in the unsaturated fatty acid, there is at least a double bond in its string. The carbon atoms that are joined by the bonds lead to the change in their shapes.

While saturated fatty acids have a linear structure, the unsaturated fatty acids kink or bend in order to form double bonds within the chemical foundation.
