The unicellular green alga chlorella is often used as a model organism to study the effects of various substances on the growth of photosynthetic organisms. Researchers studying the detoxification of certain metals by chlorella first collected data on the growth dynamics of the alga. A small number of chlorella were added to 1,500 ml of culture medium that contained all of the inorganic nutrients needed for growth. Every five days for 30 days, the researchers performed multiple counts to determine the concentration of chlorella in the culture (table 1).

Plants bend towards the light due to a phenomenon known as phototropism.

Phototropism is the growth response of a plant to light. The plant hormones, such as auxins, play a crucial role in the bending of the plant towards the light source.

The auxins are unevenly distributed in the plant cells, with a higher concentration on the shaded side. This causes the cells on the shaded side to grow longer, resulting in the bending of the plant towards the light source.

Peristalsis are the waves like contractions that help in moving food along the digestive tract.

The muscles that line your gastrointestinal track automatically contract and relax in a wave-like motion known as peristalsis. Peristalsis, which starts in the throat when you swallow and continues through the esophagus, stomach, and intestines as you digest, is the movement of food through your digestive system.

Through the myenteric plexus, the parasympathetic nervous system (PNS) stimulates peristalsis. The myenteric plexus' afferent (sensory) nerves transmit data to interneurons inside the plexus. Interneurons interact with efferent nerves to cause smooth muscle cells to produce an action potential (spike-wave).

Answer:

Ribosomes

Explanation:

hope this helps!

The student should avoid light in the wavelength range of 550-600 nm due to lack of pigments.

To measure the activity of the chloroplasts at different wavelengths, the student needs to use a broad range of light wavelengths and avoid using a specific wavelength of light that the chloroplasts cannot absorb.

Of the options given, red light (which has a wavelength range of 620 nm to 750 nm) would be the best choice to avoid in the experiment. This is because red light is absorbed strongly by chlorophyll a and b, which are the primary pigments involved in photosynthesis, and it may interfere with the measurement of activity at other wavelengths.

On the other hand, blue, orange, yellow, and violet light are not strongly absorbed by chlorophylls and can be used in the experiment to measure activity at different wavelengths.

Answer:

During cellular respiration, glucose becomes more oxidized as it is broken down and releases energy.

Explanation:

During cellular respiration, glucose undergoes a process of oxidation. In other words, it becomes more oxidized as it is broken down into smaller molecules and releases energy.

Oxidation is a chemical reaction in which a molecule loses electrons, making it more positively charged. During cellular respiration, electrons are stripped from glucose and transferred to oxygen, which combines with hydrogen ions to form water. This transfer of electrons results in the conversion of glucose into smaller, more highly oxidized molecules, such as carbon dioxide and water.

Rough endoplasmic reticulum is the system of membrane saccules that is studded with ribosomes and capable of producing proteins.

What do you mean by membrane?

A membrane is a thin, semi-permeable barrier that separates two environments, such as cells or organelles inside a cell, or the body and its environment. It is typically composed of lipids, proteins, and carbohydrates that are arranged in a phospholipid bilayer. Membranes allow certain substances to pass through while blocking others, thus regulating the movement of materials and energy.

Rough endoplasmic reticulum (ER) is a network of interconnected membranes within the cell that extends throughout the cytoplasm. It has a rough appearance due to the presence of ribosomes attached to the outer surface of the membrane. These ribosomes are responsible for the production of proteins. The ER is the site of protein synthesis as the ribosomes attached to the outer membrane of the ER synthesize proteins according to the instructions of the messenger RNA (mRNA). The proteins that are produced in this process are then transported to other compartments of the cell, such as the Golgi apparatus, for further processing.

The right electrode will be positive and the voltmeter will show a voltage of approximately 0.762 volts.

In a galvanic cell, the electrode that is immersed in the solution with a higher concentration of ions will have a lower concentration of electrons and will become the positive electrode, while the electrode immersed in the solution with a lower concentration of ions will become the negative electrode. The voltage is a measure of the potential difference between the two electrodes, and is proportional to the logarithm of the concentration ratio of the ions in the two solutions.

In this case, since the concentration of M(NO3)3 is much higher in the left half-cell than in the right half-cell, the left electrode will become the negative electrode and the right electrode will become the positive electrode, with a voltage of approximately 0.762 volts as measured by the voltmeter.

Microspore is the male spore known as in angiosperm reproduction.

Micropore are small haploid structures that develop to the male gametophyte,whereas megaspore develop into female gametophyte

The microspore divides by mitosis producing two cells. The first of the cells (the generative cell) is small and is formed inside the second larger cell (the tube cell). The members of each part of the microspores separate from each other. A double-layered wall then develops around each microspore.

These steps occur in sequence and when complete, the microspores have become pollen grains. Microspore embryogenesis is said used in biotechnology to produce double haploid plants, which are immediately fixed as homozygous for each locus in only one generation. The haploid microspore is then stressed to trigger the embryogenesis pathway and the resulting haploid embryo then doubles its genome spontaneously. Without this double haploid situation, there are several breeding methods of the generations of selection to produce a pure homozygous line.
