Answer:

Cell therapies would use stem cells, or cells grown from stem cells, to replace or rejuvenate damaged tissue. Scientists also want to use stem cells to understand disease and find drugs that might treat it. Embryonic stem cells could be used to make more specialized tissues that have been lost to disease and injury

The researchers prefer to use embryonic stem cell in medical research as Embryonic stem cells are able to differentiate into a wider range of call than adult 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.

Answer:

C.Pharynx

Explanation:

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.

The change in the tilt of the Earth can affect the distribution of sunlight and thus influence temperatures on Earth.

The 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.

positive feedback, because the response intensifies the original stimulus

Explanation:

The release of it is increasing contractions making it positive

The hormone oxytocin is released to increase contractions during childbirth, and the pathway is activated with pressure from the baby's head against the opening of the uterus, so it is a positive feedback because the response intensifies the original stimulus that is present in the third option.

Oxytocin, a hormone that plays an important role in the process of childbirth, is produced in the posterior pituitary during labor, and oxytocin is responsible for stimulating contractions of the uterus, which help to push the baby through the wall of the uterus. Oxytocin makes the bond between a mother and her newborn baby, as it is released in large amounts during childbirth and breastfeeding and helps to create a strong emotional bond.

Hence, the hormone oxytocin is released to increase contractions during childbirth, and the pathway is activated with pressure from the baby's head against the opening of the uterus, so it is a positive feedback because the response intensifies the original stimulus that is present in the third option.

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.

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;

Answer:

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.

Explanation:

release of energy through the breakdown of glucose

The release of energy through the breakdown of Glucose means Photosynthesis.

Photosynthesis 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.
