Answer:

Prokaryotes

Explanation:

One of the kingdoms of nature is called Protist Kingdom, being characterized by the eukaryotic cellular organization, that is, with organized nucleus. Their representatives may be autotrophs, thus producing their food through photosynthesis, or even heterotrophs, which are those who do not photosynthesize. They may also be unicellular or multicellular, comprising, in their realm, beings such as protozoa, myxomycetes and algae. Protists are the simplest and most abundant form of life on earth today.

Tema [17]

Answer:

See the answer below

Explanation:

Anthers release pollen, which lands on the stigma of another flower of the same species. The pollen grain produces a pollen tube that grows down the style, to the ovary, and into the ovule. The sperm cell fertilizes the egg cell. The ovule develops into the seed, and the ovary becomes the fruit.

<em>During fertilization in plants, the anther which carries pollen releases pollen grains. Once the pollen lands on the stigma of a flower of the same species, it germinates. The pollen grain produces a pollen tube that grows through the style of the stigma down to the ovary and into the ovule. One of the sperm cells fuses with the egg cell of the ovule to form the zygote while the other sperm cell fuses with the polar nuclei to form the endosperm in a process known as double fertilization. After fertilization, the fertilized ovule becomes the seed and the ovary becomes the fruit. </em>

Vsevolod [243]

Answer:

Antioxidants help cells perform their functions against something called free radicals. Free radicals are molecules that happen to be produced when your body breaks down food and/or when you inhale or are exposed to tobacco products. These molecules play a role in leading to diseases such as; Heart disease and cancer. When plants synthesize, they collect many non-enzymatic Antioxidants like ascorbic acid and phenolic. Since plants have many more sites of ROS generation, Therefore, they could evolve more efficient non-enzymatic Antioxidant systems than humans because of their high intake and exposure to oxygen. (answer yourself about the structure in your own words using the information I gave you). Diet relates to both the function, structure and health of your cells. Having a balanced diet helps your cells to happily work and produce energy for your daily use. A balanced diet supplies your body with nutrients so it can work effectively. Without balanced nutrition, your body is way more prone to disease, fatigue, low performance and infections.

Oxytocin and alcohol

Explanation:

Oxytocin helps to relax the muscles of the breasts and induce lactation in a breastfeeding mother. This hormone is commonly called the cuddle hormone since it helps to create the social and emotional bond between the child and the mother.

Alcohol clearly inhibits the secretion of oxytocin and breastfeeding immediately after alcohol consumption can reduce lactation and milk intake by the child. Maintaining an interval after an alcoholic drink again leads to delayed breastfeeding. Intoxicating levels of alcohol in breast milk can affect the child’s health.

luda_lava [24]

Answer:

A flat sheet of connective tissue that extends beyond the muscle fibers to attach the muscle to bone is a TENDON.

Explanation:

Tendon can be described as a fibrous connective tissue which functions mainly to attach muscles to bones hence, playing a major role in the movement of the bone or structure. Tendons also function to connect muscles to other structures like the eye ball.

Contrary to the tendons, ligaments are also fibrous connective tissues which are involved in the attachment of bone to bone. Hence, ligaments play major role in holding the structures and keeping them stable.
