Well allliving organisms contain genetic information, stored in DNA and RNA molecules,which directs the functions of cells.
The general coding and structureof these molecules is universally shared by all organisms. Questions about theorigin of these molecules are fundamental to our understanding of the origin oflife on Earth.
Experimentslike the one conducted by Miller and Urey demonstrated that organic moleculescould have formed spontaneously in Earth's early atmosphere, and smallermolecules could bond together to build large organic molecules. Somescientists hypothesize that some of the first large organic molecules to formand self-replicate were RNA molecules, with DNA molecules forming much later. This is called the RNA worldhypothesis.
These early RNA molecules were probably smaller than the RNAmolecules in our cells today. They would have contained the codes for buildingspecific protein molecules from the amino acids present on Earth at that time.Proteins are necessary components of all living cells.
It means that all of us- every living creature- was built off the same genetic code.
d. an opening specified for waste removal is present
Bears remove undigested food through an opening designated for waste removal, also known as the anus. This is characteristic of an alimentary canal system where food enters orally and waste leaves through a separate exit. This type of digestive system is referred to as monogastric.
In the case of bears, and other animals with a similar monogastric digestive system, the undigested food is excreted via an opening designated for waste removal as suggested in option D. The process begins in the mouth where food is broken into small particles. This food then travels to the stomach where digestion continues with the breakdown of large molecules. The digested nutrients are then absorbed into the body in the intestines. Any undigested food that is not absorbed is removed as feces through an opening known as the anus. This type of digestive system is also known as an alimentary canal, which is a complete system with an oral intake and a separate waste removal opening.

The adrenal gland sits atop each kidney
The adrenal glands are small, triangular-shaped endocrine glands located on top of each kidney. They are composed of two parts: the outer adrenal cortex and the inner adrenal medulla.
The adrenal glands play a crucial role in producing and releasing various hormones that are essential for regulating metabolism, responding to stress, maintaining fluid balance, controlling blood pressure, and supporting immune function.
The hormones produced by the adrenal glands include cortisol, aldosterone, adrenaline (epinephrine), and noradrenaline (norepinephrine).

Answer:
cross-pollination. He cross pollinated parents with different traits.
Explanation:
Gregor Johann Mendel was a great scientist/ Biologist that was born on the 20th day of the month of July, in the year 1822 in Czechia and he died on the 6th day of January, in the year 1884. Gregor Johann Mendel made significant effect on the aspect of genetics and heredity in Biology and science generally.
If you look at the world today, you are going to see beautiful and improves varieties of plants and animals which are known as hybrids.
For his research on inheritance, he cross pollinated parents with different traits to produce offsprings.
a. True
b. False
Answer:
a. True
Explanation:
Proteins are biopolymers composed of amino acids that appear in chains. These amino acids are formed by peptide bonds. Due to the functions they carry out, proteins are essential for the existence of life. Proteins can be found in both animals and vegetables. In animals, there are proteins that help protect the body, others are in charge of regulating metabolism. On the other hand, in plants proteins participate in cell division processes, membrane transport, catalysis of biochemical reactions, photosynthesis and respiration processes, synthesis of sugars, starches, and other compounds.
True. Protein can be found in both animals and vegetables. Therefore, option (A) is correct.
All living species need amino acid-based proteins to shape, function, and regulate their cells and tissues. Meat, poultry, fish, eggs, and dairy are protein-rich. These sources often supply all needed amino acids.
Proteins in vegetables and plant-based diets differ from animal-based proteins. Plant-based protein sources include legumes, soy, nuts, seeds, and grains like quinoa and amaranth. A balanced amino acid profile can be achieved by eating a variety of plant-based proteins. Therefore, option (A) is correct.
