Weak genetic organisms and strong genetic similarities in distantly related organisms.
In times of stress, the brain stimulates the adrenal glands to produce hormones including epinephrine and norepinephrine, which aid in dealing with the 'fight or flight' response. The adrenal cortex also manages longer-term stress responses through the production of corticosteroids such as aldosterone in response to ACTH.
During times of stress, the brain activates the sympathetic nervous system and signals the adrenal glands to produce hormones that assist in managing this stress. Among these hormones are epinephrine and norepinephrine (also known as adrenaline and noradrenaline), which are produced by the adrenal medulla. These hormones regulate the acute 'fight or flight' response to stress, with physiological effects such as increased heart rate, blood pressure, and blood glucose levels. Acetylcholine stimulates the release of these hormones in response to neural impulses from the hypothalamus.
Meanwhile, the adrenal cortex is involved in managing long-term stress responses through the production of corticosteroids, stimulated by the hormone adrenocorticotropic hormone (ACTH). ACTH is triggered by Corticotropin-releasing hormone (CRH) from the hypothalamus. These corticosteroids, such as aldosterone, can influence fluid retention and blood volume, thus affecting blood pressure.

B) osteoclasts
C) osteoblasts.
D) osteocytes.
E) osteogenic cells
Answer:
Osteoclasts.
Explanation:
Osteoclasts may be defined as the cells that helps in the breakdown of the bone tissue. Osteoclast plays an important role in the maintenance of the bone structure.
Osteoclasts cells are found in the small depression of the endosoteal surface. This is also known as Howship's lacunae. They shows the foamy appearance in the cell. The osteoclast can form the specialized cell membrane known as ruffle border.
Thus, the correct answer is option (B).
The provided statement stating that the rabbits are born to be blind," is true.
Rabbits are born blind. At birth, their eyes are closed, and they rely primarily on their sense of touch and smell to navigate and locate their mother for nursing. It takes a few days for their eyes to open, and their vision gradually develops over the following weeks.
Rabbits are small, furry mammals belonging to the family Leporidae. They are herbivorous animals found in various habitats around the world, except for Antarctica. Rabbits have long ears, a compact body, and strong hind legs adapted for swift movement and jumping. Rabbits are popular as pets due to their small size, cute appearance, and relatively low maintenance requirements.

b. ecological footprint
c. agriculture
Answer:
Biodiversity
Explanation:
The three options given don't seem to be correct...
Sustainability is how biological systems remain diverse and productive.
Ecological Footprint is the impact of human activities measured in terms of the area of biologically productive land and water required to produce the goods consumed and to assimilate the wastes generated.
Agriculture is the science of raising plants and/or animals for food, clothing or other useful products or the practice of cultivating the land or raising stock.
Biodiversity is a term that describes the number and variety of species that live in an area. It contributes to the stability and balance of ecosystems and provides ecosystem services.
Biodiversity is a term that describes the number and variety of species that live in an area. It refers to the variety of life on Earth, including plants, animals, and microorganisms. Biodiversity is important because it contributes to the stability and balance of ecosystems, and provides ecosystem services such as pollination, nutrient recycling, and water purification.
