The appropriate word to fill into the blank would be accessory.

In the Fall of the year, leaves appear red, orange, yellow, and brown because the chlorophyll decreases in the leaves and allows the accessory pigments to reflect mostly colors other than green.

The core pigment in leaves that makes them appear green is chlorophyll. The pigment is primarily responsible for absorbing light energy to drive the photosynthetic process in plants.

Some other pigments, also known as accessory pigments such as carotenoids, anthocyanins, xanthophylls, etc., help out chlorophyll in some ways but have colours that are different from green.

Thus, the appearance of other colours such as orange, yellow, brown, etc., on leaves is due to a decrease in chlorophyll and the reflection of the colours of the accessory pigments.

The hormone that directly opposes the actions of natriuretic hormones is aldosterone.

Aldosterone is a hormone produced by the adrenal glands, specifically the adrenal cortex. It acts on the kidneys to promote the reabsorption of sodium ions and the excretion of potassium ions.

Natriuretic hormones, on the other hand, promote the excretion of sodium ions and the reabsorption of potassium ions in the kidneys, leading to increased urine production and decreased blood volume.

Therefore, aldosterone counteracts the effects of natriuretic hormones by increasing sodium reabsorption and reducing potassium excretion, which helps to retain water and maintain blood pressure.

In summary, while natriuretic hormones promote sodium excretion and water loss, aldosterone works in the opposite direction by promoting sodium reabsorption and water retention.

Glands that have branched ducts and secretory cells that form sacs at one end of the ducts are called compound alveolar glands.

The exocrine gland secretes enzymes outside the gland through the duct. The gland can be unicellular, multicellular, compound, tubular, alveolar, etc. Their modes of functions vary too. An example of an alveolar gland is the mammary gland. Sweet glands are an example of tubular glands.

Hence, glands having branched ducts and sac-like secretory cells are called compound alveolar glands.

density-independent factor

Explanation:

density-independent factor, also called limiting factor, in ecology, any force that affects the size of a population of living things regardless of the density of the population (the number of individuals per unit area).

hope this helped!!!! have a great day!

An environmental factor such as storms and extreme heat or cold that affects population regardless of their density are known as density- independent factors.

Density- independent factors are type of limitation factors that affects the population size in specific environment regardless of the density of that population.

Density of population can be defined as number of individuals per unit area.

DNA Synthesis

In preparation for cell division, the cell makes a replica of its entire DNA. This happens during the S, or synthesis, phase of the cell cycle. Mitosis is the division of one cell into two cells that each has a nucleus and the same amount of DNA as the original cell.

Answer:

B.

Explanation:

Because if they have traces of RNA in them, then it might be the first genetic material

Answer:

Nondisjunction

Explanation:

Nondisjunction occurs when homologous chromosomes or sister chromatids fail to separate during meiosis, resulting in an abnormal chromosome number. 

A red onion cell placed in a saline solution will lose water when water moves from the cell to the surrounding hypertonic medium via osmosis, causing the cell to shrivel up.

The passage of solvent molecules from a lower concentration solution to a higher concentration solution across a semipermeable membrane. It is a passive process that occurs without the use of any energy.

Solvent molecule transfer proceeds from low to high concentration regions until the concentrations on both sides of the membrane are equal.

Thus, we can conclude that when a red onion cell is placed in salt water.

As we can see in the diagram the onion cell shrink which means it is placed in salt water which is a hypertonic solution.

So, option (3) salt water is correct.

Answer:DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded.

Explanation:

DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded.  DNA could get damaged because of the osmotic nature of cytoplasm. Therefore, option (C) is correct to mitigate he damage.

The proteins are produced by cells by the transcription and translation of certain genes from their DNA into molecules of messenger RNA (mRNA), chains of amino acids, and finally fully functioning proteins.

The DNA would need to go to the cytoplasm in order to directly make proteins. Because of the osmotic properties of cytoplasm, DNA may become damaged during the translocation process. The cellular machinery does not directly make proteins from DNA in order to reduce the harm.

Explanation:

Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. ... Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms

The preserved remnants or traces of extinct animals, plants, and other organisms are known as fossils. Because they demonstrate that earlier life on Earth was distinct from the life observed today, fossils are crucial pieces of evidence for evolution.

According to the idea of evolution, modern life forms have evolved from more ancient ones.

The original theory suggested that this occurred slowly and gradually, but fossil evidence suggests that the process occasionally went wrong and engaged in some very bizarre experiments.

Therefore, they demonstrate that earlier life on Earth was distinct from the life observed today, fossils are crucial pieces of evidence for evolution.

Answer:

No

Explanation:

Arteries typically carry oxygenated blood, which is bright red in colour. The exception is the pulmonary artery which carries deoxygenated blood from the heart to the lungs.

Answer:

Venules carry deoxygenated blood. All blood in humans is bright red when oxygenated, but, a darker red when deoxygenated. Deoxygenated blood is darker due to the difference in shape of the red blood cell when oxygen binds to haemoglobin in the blood cell (oxygenated) versus does not bind to it (deoxygenated).

Explanation:

Conditions necessary for germination are :

Temperature/Warmth

Oxygen/Air

Water/Moisture

Answer:

The oxygen molecule enters the human body from the mouth or nose and reaches the phraynx and then the larynx, trachea and the bronchus. It then enters the lungs which then the red blood cells takes the oxygen from the blood and carries it to the muscle in the arm.

The pathway of an oxygen molecule from the air outside your body to a muscle cell in your arm involves several sequential steps, including inhalation, gas exchange in the lungs, transportation through the bloodstream, and diffusion into muscle cells.

During inhalation, you breathe in air through your nose or mouth. The air travels through your respiratory system, passing through the trachea (windpipe) and into the bronchi, which branch into smaller tubes called bronchioles. Eventually, the inhaled air reaches the alveoli, tiny air sacs located at the end of the bronchioles in the lungs.

In the alveoli, oxygen molecules diffuse across the thin walls of the air sacs and into the surrounding capillaries. Oxygen diffuses from an area of higher partial pressure (in the alveoli) to an area of lower partial pressure (in the capillaries). Hemoglobin, a protein within red blood cells, binds to the oxygen molecules in the capillaries, forming oxyhemoglobin.
