Fill the blankstarch and glycogen are similar to each other in that _______. however, _______.

Answers

Answer 1

Starch and glycogen are similar to each other in that they are both polysaccharides made up of glucose monomers. However, there are also some differences between starch and glycogen.

Both starch and glycogen are storage carbohydrates that serve as a source of energy for the organism. They are also both branched polymers of glucose, meaning that they have many glucose molecules linked together in a complex branching structure.

One major difference is that starch is found in plants, while glycogen is found in animals. Another difference is that glycogen has more highly branched chains than starch, allowing for more efficient storage and release of glucose.

Of the following plants, which stem has scattered vascular bundles? A. corn B. magnolia C. chrysanthemum D. hibiscus

Answers

Of the following plants, a. corn stem has scattered vascular bundles.

How do vascular bundles work?

The transport system in vascular plants includes vascular bundles. The actual transport takes place in the stem, which comes in the xylem and phloem forms. A vascular bundle, which also contains supporting and protecting tissues, contains both of these tissues. The Cambium, a tissue, is also present between the xylem and the phloem.

Phloem is often found farther from the axis than the xylem, which is typically adaxial (abaxial). This indicates that in a stem or root, the xylem is closer to the interior while the phloem is closer to the exterior. The upper side of a leaf is typically the adaxial surface, and the bottom side is the abaxial surface.

Answer:

Anaphase

Explanation:

After anaphase, a cleavage furrow forms in the equatorial cortex in typical animal mitosis. To divide the two daughter cells, this furrow then progresses inwards.

The sister chromatids differentiate from each other in anaphase and are pulled toward opposite ends of the cell. The "glue" of protein that binds together the sister chromatids is broken down, causing them to separate. Each one now has a chromosome of its own.

what group of animals exhibits spiral cleavage and includes acoelomate, pseudocoelomate, and coelomate animals?

Answers

The group of animals that exhibits spiral cleavage and includes acoelomate, pseudocoelomate, and coelomate animals is the Protostomes. This group includes a wide range of invertebrate animals such as mollusks, arthropods, annelids, and nematodes.

Protostomes undergo spiral cleavage during embryonic development, which is characterized by the division of cells at oblique angles to each other. This pattern of cell division determines the formation of tissues and organs in the developing embryo. The protostome body plan also includes a mouth that develops from the blastopore, which is the opening formed during early embryonic development.

The three main subgroups of protostomes include acoelomates, pseudocoelomates, and coelomates. Acoelomates lack a body cavity, while pseudocoelomates have a body cavity that is not completely lined by mesoderm. Coelomates have a true body cavity that is completely lined by mesoderm.

Overall, protostomes are a diverse and fascinating group of animals that exhibit unique developmental and anatomical features.

Explain how organelles and other structures interact to secrete substances from the cell.

Answers

Answer:

Organelle and other structures have vessels that are collectively referred to as the endomembrane system

The interaction of organelles and other structures to secrete substances from the cell is as follows:

Cell secretion is a long-lasting process by which a cell directs secretory vesicles out of the cell membrane.

In exocytosis, the proteins or molecules produced in the endoplasmic reticulum are enveloped in a vesicle towards the Golgi apparatus.

The substances pass through all the saccules of the Golgi apparatus and when they reach the trans face of the dichthyosome, in the form of secretory vesicles.

These are transported to their destination outside the cell, crossing the cytoplasmic membrane by exocytosis.

Golgi apparatus not only communicates with the membrane but with all the organelles found inside the cell, including peroxisomes and mitochondria.

Therefore, we can conclude that the reticulum and Golgi apparatus participate in secretion of substances from the cell, the vesicles fuse in the plasma membrane, thus releasing their content to the extracellular medium.

Cancer consists of too much cell division. Mutated genes do not work properly as the instructions in their DNA gets mixed up. This causes cells that should be resting to divide and grow out of control, which leads to cancer.

What happens in cancer?

Uncontrolled cell growth is cancer. Gene mutations can increase the pace of cell division or suppress natural mechanisms that keep the body in check, like cell cycle arrest or programmed cell death. A tumor can form as a collection of malignant cells enlarges.

Cancer cells frequently proliferate rapidly without having time to develop. The cells don't function correctly since they aren't fully developed. They also have a larger possibility of picking up more genetic errors because they divide more quickly than usual.

Answers

Prolonged exposure to any sounds above 85 decibels can produce hearing loss (Option D).

What is a decibel?

The decibel (dB) is a unit of measurement for sound levels. It is used to measure the magnitude of sound, and it is commonly used in the music industry and sound engineering. The decibel scale is logarithmic, meaning that a small increase in decibel level corresponds to a significant increase in the sound's actual energy.

The human ear can detect sounds as low as 0 decibels and as high as 140 decibels. Prolonged exposure to any sounds above 85 decibels can produce hearing loss, and prolonged exposure to sounds above 130 decibels can cause immediate damage to the ear's hearing structures.

Explanation:

The independent variable is the manipulatable variable supplied into an experiment. It is a variable that directly affects the dependent variable.

The independent variable is the outcome variable. It is the variable that is primarily measured from experiments whose value depends on the value of the independent variable.

The control variables are those that are kept constant throughout the course of experiments. In other words, they do not directly affect experimental outcomes.

Pyruvate stands at a metabolic crossroads. Indicate the necessary enzymes needed to convert pyruvate into the following metabolic products, Pyruvate + Alanine: Pyruvate dehydrogenase Pyruvate decarboxylase Pyruvate + Oxaloacetate: Lactate dehydrogenase Pyruvate carboxylase Transaminase Pyruvate -- Acetaldehyde: Pyruvate Lactate: Pyruvate Acetyl-COA

Answers

Pyruvate is a key molecule that stands at a metabolic crossroads, where it can be converted into different metabolic products depending on the necessary enzymes available in the cell.

To convert pyruvate into pyruvate + alanine, the necessary enzyme is pyruvate transaminase, which transfers the amino group from alanine to pyruvate. To convert pyruvate into pyruvate + oxaloacetate, the necessary enzymes are pyruvate carboxylase and transaminase. Pyruvate carboxylase adds a carboxyl group to pyruvate to form oxaloacetate, and transaminase transfers an amino group to pyruvate to form alanine. To convert pyruvate into acetaldehyde, the necessary enzyme is pyruvate decarboxylase, which removes a carboxyl group from pyruvate to form acetaldehyde. To convert pyruvate into lactate, the necessary enzyme is lactate dehydrogenase, which reduces pyruvate to lactate by using NADH as a cofactor. Finally, to convert pyruvate into acetyl-CoA, the necessary enzyme is pyruvate dehydrogenase, which removes a carboxyl group from pyruvate to form acetyl-CoA, which can enter the citric acid cycle for further energy production.
