what does photosynthesis mean ?
state it's equation.
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Answer:
photosynthesis is a process in which plants make there own food

1 Identify the hormones (and their functions) of the hypothalamus and the anterior and posterior pituitary glands in homeostasis.
2 Detect the endocrine glands on models and charts and their histological properties in the microscope.
3. Analyze the effects of aging, imbalances, and diseases of the endocrine system.
1.The hormones of the hypothalamus and the anterior and posterior pituitary gland are antidiuretic hormone and oxytocin and ADH.
What hormones are produced by the hypothalamus and their functions?The hormones produced by the hypothalamus and secreted by the neurohypophysis are antidiuretic hormone and oxytocin. Antidiuretic hormone promotes an increase in urine concentration, as it ensures greater reabsorption of water by the kidneys.
2. The endocrine glands on models are :
hypothalamus.Hypophysis. Thyroid gland.Parathyroid glands.Islet cells of the pancreas.Adrenal glands. Testicles in men and ovaries in women.What are the general characteristics of the endocrine glands?The main feature of endocrine glands is the absence of excretory ducts. The service product produced by endocrine cells is transported to the extra diffusion space, reaching the interior of blood vessels.
3. When an imbalance of the endocrine system occurs, it results in Hormonal disorders can be caused by various factors such as diabetes, psychological changes, stress, eating disorders, regular use of medication and cancer.

Tea leaf. Light micrograph of a cross-section through a tea (Camellia sinensis) leaf. The upper and lower epidermis on the surfaces of the leaf are blue. Under the upper epidermis are palisade cells (brown), which contain chloroplasts, the site of photosynthesis. Beneath this a spongy mesophyll layer with large spaces between the cells. At bottom left, a stoma (pore) is seen. Stomata allow gases and water to enter and leave the plant. Magnification: x230 when printed 10 centimetres wide.

Hunting in the area causes all of the shrews in the area to be
killed. How would this affect the rest of the organisms in the
food web?
Answer:
C: the number of crickets would increase
Explanation:
If less shrews were to exist than their prey would increase because they have less predators.
On a piece of paper, or using the pointer draw in word, draw 6-10 water molecules in the arrangement they would take when water frozen into ice.
Is frozen water more or less dense than liquid water? How do you know (what about your model supports this)?
Why does frozen water take on the pattern it does (hint: it has to do with water’s polarity)?
Plants must get water from their roots to their highest branches. Explain how cohesion and adhesion might help a plant get water from the ground to its upper leaves.
Support your answer with a model
Frozen water is less denser than liquid water so that's why ice floats on the water in cold areas.
Is frozen water more or less dense than liquid water?Ice is less dense than liquid water because when the water becomes solid due to low temperature, the density of ice become decreases. Due to less density, the ice floats on the water surface.
Water is attracted due to its polar nature so adhesive forces pull the water toward other molecules. Water is transported in plants through both cohesive and adhesive forces. These forces pull water and the dissolved minerals from the roots to the upper parts of the plant.
So we can conclude that frozen water is less denser than liquid water so that's why ice floats on the water in cold areas.

Julia is trying to place a duckbilled platypus, lizard, bear, and monkey on a phylogenetic tree. She learns that the duckbilled platypus, bear, and monkey are classified as mammals. She also learns that mammals share a common ancestor with reptiles. Which additional piece of information will be most helpful to Julia to properly build her phylogenetic tree
The additional information required is that the platypus lays eggs like a reptile.
What are mammals?The animals classified as mammals are those animals that give birth to their young ones alive and also possess the mammary gland. As such, they can breastfeed their young ones.
Since the mammals share a similar ancestry as the reptiles, the additional information that Julia requires is that the platypus lays eggs like a reptile.
