A glucocorticoid hormone is cortisol molecules.
What changes does cortisol make to the body?The primary stress hormone, cortisol, elevates blood sugar (glucose), enhances the brain's ability to use it, and increases the amount of substances that can be used to repair cells.Cortisol also inhibits physiological activities that would be superfluous or harmful in a fight-or-flight situation.
What signs point to high cortisol levels?An overabundance of cortisol can cause some of the telltale signs of Cushing syndrome, along with a fatty hump between both the shoulder, a round face, or pinkish-purple stretch marks just on skin.Cushing syndrome can occasionally also cause type 2 diabetes, elevated blood pressure, or bone loss.

Q1. Celery is a plant that is harvested for food.
The celery stem is made from xylem tissue, phloem tissue and epidermal
tissue.
Is the celery stem an organ or an organism?
Choose the best answer to this question.
A. An organism because plants are living things
B. An organism because it is made of several different organs
C. An organ because it is made of several different tissues
D. An organ because it is made of the same type of cells
Celery is an organ because it is made of the same type of cells.
What is celery?
A piece of celery contains the plant's petiole, or stem, which humans consume. The type of cells found in celery tissue account for the stalk's crunchiness.Celery also has collenchyma tissue, which supports the plant, in addition to the vascular bundles of xylem (water-conducting) and phloem (food-conducting) tissues. The pressure of the water pressing against the cell walls gives collenchyma tissue, which is made up of elongated live cells packed with water, its rigidity, which gives celery its crunch.Plant stems, leaves, and flowers all contain collenchyma. The collenchyma tissue on a celery stem is found on the ribs along the exterior of the stalk and on the interior.Hence, celery is an organ

In which type of rock would you find a large amount of silica?
Responses
glass

igneous
sedimentary
Answer:
igneous
Explanation:
Igneous rock is the type of rock that contains a large amount of silica. Igneous rocks are formed when molten rock (magma or lava) cools and solidifies. Silica is a common component of magma, so igneous rocks are often rich in silica. Glass, which is also made from silica, is not a type of rock. Metamorphic and sedimentary rocks are formed through processes that do not involve the melting of rock, so they typically contain lower amounts of silica.

Eukaryotic cells, which have a nucleus encircled by the nuclear membrane, are the building blocks of large and complex organisms. Protozoa, animals, plants, fungi, and plants all contain eukaryotic cells. They are classified as being part of the kingdom Eukaryota. They can withstand a variety of circumstances in a single cell, allowing them to carry out different metabolic functions. This allows them to expand many times more than prokaryotic cells. Eukaryotic cells have the following characteristics: In eukaryotic cells, the nuclear membrane encloses the nucleus, the cell's mitochondria. Flagella and cilia are the locomotory structures found in eukaryotic cells. Cell walls are the word for eukaryotic cells' outermost layer. Cells divide via the mitotic process.

Synapsis, a mechanism where homologous chromosomes couple based on sequence similarity, accomplishes this.
In a chromosome body known as a tetrad (because it contains 4 replicated chromosomes known as chromatids) or bivalent, the homologous chromosomes are bound together by a protein structure known as the synaptonemal complex (if the organism is diploid). The homologous chromosomes can recombine thanks to this pairing during prophase 1 of meiosis. This happens early in prophase, although the recombination's manifestation is not obvious until late in prophase 1 and during metaphase 1.
