Answer:
The organs of the male reproductive system are specialized for three primary functions: To produce, maintain, transport, and nourish sperm (the male reproductive cells), and protective fluid ( semen ). To discharge sperm within the female reproductive tract. To produce and secrete male sex hormones.
The answer is <span>adrenal gland.
</span><span>Hormones are chemical signaling
molecules secreted by glands, either endocrine or exocrine. </span><span>Endocrine glands secrete hormones
directly into the bloodstream without using a duct,
unlike the exocrine glands. Endocrine
glands include pancreas, hypothalamus, pineal gland, pituitary gland, thyroid
gland, parathyroid gland, adrenal gland, ovaries, testes</span>
Answer:
1. Head, neck, upper limb, thorax - super vena cava - top of the right atrium.
2. Lower limb - inferior vena cava - bottom of the right atrium.
Explanation:
The Heart pumps the oxygen-rich blood to the different parts of the body to Otake oxygen and nutrients to these organs and then takes the oxygen-poor blood returns from the body to the heart.
The two major vessels that return oxygen-poor blood to the heart are 1. superior vena cava (SVC) that drainages Head, neck, upper limb, thorax and terminate at top of the right atrium, and 2. inferior vena cava (IVC), Lower limb and terminate at bottom of the right atrium.
1. Head, neck, upper limb, thorax - super vena cava - top of the right atrium.
2. Lower limb - inferior vena cava - bottom of the right atrium.
It represents genetic drift so D! please give me brainly!
As the new species of plant produced purple flowers, so, the plant belongs to the angiosperms group. Also, the seeds of the plant contain two embryonic leaves, so, the plant must be a dicot.
- Out of all five divisions of plants, only the plants that come under the Division Angiosperm can bear or form flowers. That's why angiosperms are also called flowering plants.
- Angiosperms are further divided into two groups based on the number of embryos that are produced from seeds on germination.
- If the germinating seeds contain only one embryo leaf, then we call them monocots while the seeds that contain two embryo leaves during their developing seeds, then they are called dicots.
Thus, the plant that is discovered by scientists comes under the angiosperm group and further into the dicot group. Dicots have two embryo leaves on germination of their seeds and they also form flowers.
