Angiosperms belong to the plant kingdom. Flowers are the organs needed for sexual reproduction, carrying feminine and masculine structures.
What are the parts of the flowers?Flowers are reproductive structures in charge of sexual reproduction through the production of seeds.
⇒ Feminine reproductive structures
The central structure is the carpel, also recognized as the pistil.The base of the carpel forms the ovary, in which the eggs are produced and where the zygote develops.The opposite extreme of the carpel is the stigma, in the superior part.The stigma is a sticky surface where the pollen grains get attached.The style is the filament structure that connects the ovary and the stigma.⇒ Masculine reproductive structures
The pollen grains, or male sex cells, are produced in the stamens.The stamen has an anther where the pollen is produced, and a filament that provides support.
⇒ External non-reproductive structures
Flowers also have external structures known as petals and sepals. These are modified leaves whose principal function is to protect the flower's fertile parts and attract pollinators.
Petals characterize as having many different colors that make the flower more attractive to insects and other animals. When they visit a flower searching for their recompense, the flower's pollen grains transfer to the insect's body.
The insect transports the pollen to the next visited flower, leaving it in the stigma of the second flower.
What happens during the fertilization process?1) The mature pollen grains are driven to the stigma of the same flower or other flowers of the species, where they stick.
2) Once in the stigma, the pollen grain germinates.
3) A pollinic tube forms. It goes from the stigma along the style and ends in the flower ovary.
4) The pollen grains move along the tube forward to the ovary.
5) Once in the ovary, the pollen grains get in touch with the ovule. They have double fertilization.
6) The zygote develops in the ovary.
Now, let us answer the questions,
1) Flower Dissection ⇒ you will find and scheeme in the attached files
2) Characteristics of the plant kingdom
eukaryotic multicellular organisms, photosynthetic organisms,cells with chloroplasts, a big vacuole, and cell wall. sexual and asexual reproduction3) Stomata regulate water vapor flow through transpiration.
Desert plants have fewer stomata than tropical plants as an adaptation to avoid losing water.
4) Having fewer stomata help protect the health of a plant by preventing excessive water loss under extreme conditions.
5) The vascular system of plants is composed of
The xylem ⇒ takes water and nutrients from the soil to the aerial part of the plant.The phloem ⇒ transports photosynthetic products to different tissues of the plant.If the xylem gets damaged, the plant will not be able to take water and nutrients from the ground. If the phloem gets damaged, the plant will not be able to use photosynthetic products in different tissues. In any case, the plant will dye.
6) Because plants and human dermal tissues vary in the number of layers and functions.
Plants have one dermal layer and have a cuticle to avoid dehydration and provide protection. Human skin is multilayered and the immune system protects it.7) Ground tissues are not meristematic, dermal, or vascular tissues. However, among their functions, we can mention photosynthesis, storage, regeneration, and healing capability. All of them are necessary to survive. If the ground tissues are damaged, the plant can not survive.
8) Flowering plants can reproduce sexually or asexually. During sexual reproduction, pollen grains fertilize the eggs in the ovary.
9) During pollination, insects and other animals get a recompense -nectar-. Flowers provide a source of food and prime matter to different pollinator agents. Also, flowers might be a shelter for many species.
10) The stamen where the pollen is produced. The ovary is where eggs are produced and where the zygote develops. Pollen gets to the egg in the ovary and fertilizes it (description above).
11)
The embryo is formed after the double fecundation. It composes of growing cotyledons, an epicotyl, and a hypocotyl.
The tegument and endosperm of the seed protect the embryo from dehydration and denutrition.
Germination is the process of development and the emergence of the embryo. These are a series of steps that must occur in the seed from the moment the embryo begins to develop until a newly emerged plantule is formed. For germination to occur, there must be appropriate environmental conditions.
12) Flowers are bright and colored because this is how they attract pollinator agents such and insects and other animals.

The target cells for the hormone ACTH are located in the _______. The target cells for the hormone ACTH are located in the _______. anterior pituitary hypothalamus adrenal cortex posterior pituitary
The target cells for the hormone ACTH are located in the adrenal cortex.
The adrenal cortex is the outer part of the adrenal gland. It produces hormones that support important organ functions and body processes. Many illnesses can affect the adrenal cortex. Some cause the overproduction of hormones, while others limit hormone production.
The adrenal glands are partially controlled by the hypothalamus and pituitary gland. The hypothalamus is a small area of the brain involved in hormone regulation that produces corticotropin-releasing hormone (CRH) and antidiuretic hormone (ADH or vasopressin).
Adrenocorticotropic hormone (ACTH) is a hormone released from the pituitary gland and plays a major role in how the body responds to stress. With the release of ACTH, the adrenal glands produce cortisol, "stress hormones", and androgens (a group of sex hormones).

what happens when solid particles gain enegry
Answer:
The solid particles eventually gain so much energy that the vibrations increase and break their fixed positions.
Explanation:
Atomic bonds hold atoms to one another inside a solid. Instead of acting like stiff rods, these linkages act like springs. A solid is thus made up of several heavy particles that are linked by springs. You may easily picture these particles continuing to oscillate erratically to and fro from their places, resulting in zero net motion. But power is still needed for this oscillation. The solid's temperature is controlled by this energy, which is also known as internal energy. The energy increases with temperature. A solid's internal net energy rises when it receives (thermal) energy. The surplus is divided among all the particles essentially evenly. The frequency in a spring mass system does not alter with energy, but the amplitude does. In other words, atomic oscillations have the same frequency but a greater amplitude. In other words, the atoms move farther throughout their oscillations. The amplitude may rise to a point where the spring-ey linkages begin to break and the lattice collapses if you provide them with enough energy. To put it simply once again, the solid dissolves.

Human skin cells are replaced every 20 days, while human brain cells last 30 to 50
years. Why would brain cells need to last for so long? Why might this be a problem if
we managed to extend human life beyond 100 years?
In this question, there is a misinterpretation of the term "cell lifetime."
The body's structural building blocks are called cells. One of the body's methods for improving performance over time is to extend cell longevity.
Blood and skin cells are examples of "deliberately" disposable cells. This is because the best method for a cell's function is cell turnover. Skin cells are harmed when they are exposed to the abrasive outside environment. A wonderful method for combating the entropy of environmental harm is to slough them off and replace them with fresh ones. Red blood cells are transient "by design" since they lack a nucleus.
The brain's neurons are tuned for a fundamentally different purpose: memory. The brain's objective is to improve throughout time by building up knowledge and memories. These abilities and memories are "stored" as subtle structural adjustments to the way the brain's neuronal connections are organized. In order to maintain that structure as long as possible, the brain must. Since cells are the only thing that exist, the structure of neurons takes the form of their peculiar cell forms, which resemble the complicated tree branches that wind through the brain. If a neuron dies, it also leaves behind its structure and memories. Therefore, neurons should never die in the brain according to ideal design. This has resulted in several safeguards for this structure, including the blood brain barrier that guards against poisoning and the hard shell of the skull. '
Long-term brain health would be an issue if humans could live longer than 100 years. We would need to make investments in preventing this catastrophic mental failure as well as create therapies to keep the brain "fresh" because the brain did not adapt to endure that long (for example, dementia).

which model best shows the movement of water during photosynthesis
Answer:
Soil → Plant
What happens in photosynthesis?
The light is energy. So the plant doesn't convert light to energy, light already is energy. The plant uses the light energy to grow, and to store energy in a different form (like how you eat corn, and gain energy to run and stuff, your body converts the corn to fat so you can use the energy later.)
Now, as for the creation of oxygen, we have to go deeper. In the air there is CO2, which is 2 parts oxygen and one part Carbon. Plants "breathe" it in. From the ground the plants get water, H2O, which is 2 parts Hydrogen and 1 part Oxygen, right? The plant uses the light energy to convert the C02 and H2O into Sugar, C6H1206 (6 Carbons, 12 Hydrogens, 6 Oxygens)
So we see that there must be 12 Hydrogens in the end, but H20+C02 only has 2. That means you need 6 H2O molecules, which fuse with 6 C02 molecules (becuase sugar has 6 carbons as well)
What we get is (6)H2+(6)C+[(6)02+(6)O] which we can algebra into H12+C6+O18. Now we subtract the sugar, which the plant stores (C6H12O6) and we are left with 012, or Twelve Oxygens. Oxygen doesn't like being alone, so we would represent it as 6 oxygen pairs (6)O2. That oxygen gets released back into the air. Boom.

How do the basic principles of inheritance which Mendel found in plants differ from those which are found in humans
The inheritance in humans is more complex as compared to the inheritance in plants as described by Mendel.
Mendelian inheritance patterns mostly refer to the inheritance of traits controlled by a single gene with two alleles. In plants, most characteristics are governed by a single gene but in humans, most of the traits are polygenic which means that they are governed by more than one gene.
Also, most of the genes in humans have more than two alleles and hence they do not follow simple Mendelian inheritance patterns.
In humans, the males have only one X chromosome (that contains sex-linked traits) and females have two X chromosomes, this also leads to more complex patterns of dosage compensation and inheritance in humans and they do not follow the basic Mendelian laws as the plants do.
