When many nucleotides link together, they form a biomolecule responsible for storing genetic information called nucleic acids. Thus, the correct option is B.
What are Nucleotides?Nucleotides may be defined as the basic unit of the polynucleotide chain of nucleic acids such as DNA or RNA. Each nucleotide is composed of three components. They are as follows:
A nitrogenous base.A pentose sugar (ribose in the case of RNA, and deoxyribose in the case of DNA).A phosphate group.Nucleotides are the monomers of nucleic acids. Each nucleotide is joined together by covalent bonds known as phosphodiester linkage. This linkage is present between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar of next nucleotide.
Therefore, nucleic acids are formed when many nucleotides link together which are responsible for storing the genetic information.

Why could the change in the tilt of Earth cause temperatures on
Earth to change?
The change in the tilt of the Earth can affect the distribution of sunlight and thus influence temperatures on Earth.
Earth's tilt and temperatureThe tilt of the Earth, known as obliquity, affects the distribution of sunlight and influences temperatures.
A greater tilt leads to more pronounced seasons, with hotter summers and colder winters, while a lesser tilt reduces the seasonal contrast. These changes occur over long timescales.
However, short-term climate variations are primarily influenced by factors like greenhouse gases, ocean currents, and atmospheric circulation patterns.

What does the word Photosynthesis mean?
A. Release of energy through the breakdown of Glucose.
B. Creating photographs.
C. Taking apart with light.
D. Putting together with light.
Answer:
A
Explanation:
release of energy through the breakdown of glucose
The release of energy through the breakdown of Glucose means Photosynthesis.
PhotosynthesisPhotosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs "light", and synthesis "putting together" Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere and supplies most of the energy necessary for life on Earth.
Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll (and other colored) pigments/chromophores. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas.

Equilibrium is when the concentration is the same throughout an entire system. Explain how a cell reaches equilibrium in all three types of solutions (hypertonic, hypotonic, and isotonic).
It is pertinent to understand what hypertonic, hypotonic, and isotonic solution means before setting out to explain how a cell reaches equilibrium in each type of solution.
A hypertonic solution is one whose solute concentration is higher than that of the sap of a cell that is immersed in it.A hypotonic solution is one with the same solute concentration as that of the sap of the cell immersed in it.An isotonic solution has a lower solute concentration than that of the sap of the cell immersed in it.In biological systems, water molecules move by osmosis from the region of higher water potential or lower concentration of solutes to the region of lower water potential or higher concentration of solute. An equilibrium is reached when there is no net movement of water between two sides. Hence;
A cell placed in a hypertonic solution will lose water to the surrounding solution until an equilibrium is reached. This means that such a cell will end up shrinking (wilting) or even dying due to loss of water from the cell sap.A cell placed in a hypotonic solution will gain water from the surrounding solution until there is no net movement of water anymore. Such a cell might become turgid or even burst out its cell content.A cell placed in an isotonic solution will neither gain nor lose water because the cell sap and the surrounding solution have equal solute concentrations.More about osmosis here: https://brainly.in/question/1213189

A person always feels hungry, even a short time after eating. This person also has high blood calcium levels. This person could have a disorder with which glands?
Hypothalamus; thyroid
Pineal; thyroid
Hypothalamus; adrenal
Pineal; adrenal
The correct glands are hypothalamus and thyroid gland.
The HYPOTHALAMUS is a part of the forebrain which is the main co-ordinating and control center for the autonomic nervous system. It plays an important role in homeostasis. It
--> regulates body temperature and the body's urges such as thirst and hunger by impulses it sends along the autonomic nervous system; and
--> controls endocrine secretions by monitoring the metabolites and hormone levels in blood.
The THYROID GLAND is an endocrine gland located in front of the larynx and trachea. This gland is known to produce a hormone called calcitonin from its parafollicular cells.
The calcitonin is secreted when there is high level of calcium in the blood, opposing the effects . Therefore it helps in the regulation of calcium levels in the blood. A disorder of the Thyroid gland can lead to absence of this hormone, calcitonin, thereby leading to high levels of calcium in the blood.
THEREFORE, the correct glands are HYPOTHALAMUS and THYROID GLAND.
PINEAL GLAND is NOT correct because it a gland located at the brain, which involves the secretion of the hormone melatonin which is associated with development of sec organs.
ADRENAL GLAND is NOT correct because the secretions from this gland helps in regulation of metabolism of the body.

What are the functions of embryonic stem cells?A blastocyst, an early-stage pre-implantation embryo, is the source of embryonic stem cells, which are pluripotent stem cells. Four to five days after fertilization, human embryos reach the blastocyst stage.
The human blastocyst, an early stage of the developing embryo that lasts from the fourth to seventh day after fertilization, contains embryonic stem cells (ESCs) in its inner cell mass. In typical undeveloped turn of events, they vanish after the seventh day.
The ability to differentiate into cell types belonging to the three germ layers (ectoderm, endoderm, and mesoderm) is what is meant by the term "pluripotent." the three distinct types of tissue that are present during embryonic development and later combine to form the adult.
