In our solar system, the sun is our closest star and it’s huge. Around 1 million earths can fit inside the sun to show you that perspective.
The sun glows so brightly because of nuclear fusion. Nuclear fission is a certain type of reaction and it releases enormous amounts of energy. Very small particles of mass create thermal energy.
Answer:
a. stem 1: Asparagus
b. taproot: 5. Carrot
c. lateral buds: 2. Brussels sprouts
d. modified stem: 6. Potato
e. leaf (petiole and blade): 4. Spinach
f. petiole: 3. Celery
Explanation:
A plant stem is one of the structural axes of vascular plants that holds structures such as leaves, flowers, and fruits. The stem also transports water and dissolved (organic and inorganic) nutrients between the roots and the shoots. In some plants, the stem is modified in order to carry out other functions (e.g., storage, vegetative propagation, protection, etc). Potatoes are modified stems (i.e., stem tubers) that are connected by small stem sections known as stolons, and serve as food storage organs. A taproot is a central, and dominant root from which other roots sprout, which can be used by the plant to store water and food (e.g., in carrots and turnips). Lateral buds or axillary buds are meristematic regions growing from the axils of the leaves at the intersection of the leaf and stem, below the terminal bud. Leaves are composed of the 1-blade, also known as the lamina, which is the largest part of the leaf, and 2-the petiole, which is a stalk that supports the blade and connects it to the plant stem. Celery petioles play the same functions as a plant stem by acting as transport and storage organs.
When the Civil War ended, the big question concerned the state of the freed slaves of the South. Recovery of the southern economy depended on getting the freedmen back into the cotton fields. During the period of Reconstruction the Radical Republicans in Congress tried to convert the freedmen into small free-holding farmers, but the former slaves were simply not ready to manage their own farms. What emerged out of necessity was southern farm tenancy, a system of near slavery without legal sanctions.
Answer:
According to what has been investigated the option that should be supported by more scientific evidence: In psoriasis plaques, there are fewer T-cell clones, but there are often a large number of T-cells representing only a small number of clones (this is called oligoclonal expansion).
Explanation:
Oligoclonal expansion does not occur only in this pathology, it also occurs in other recurrent diseases such as multiple sclerosis, this phenomenon is widely studied and little discovered in some aspects and is mainly based on both tcd4 and tcd8 and b lymphocytes.
In this case, the presence of ltcd4 in psoriasis is very versatile and depends on the patient's immune response, which is why more scientific evidence is needed on this topic, based mostly on meta-analyzes.
the answer for the first one is B
