Answer:

Fresh water has a variety of different sources on Earth which includes rivers, lakes, streams, rain water, etc.

One of the fresh water sources is a Lagoon which is a permanent shallow body of water which is separated from the larger water bodies by a natural barrier such as reefs or islands.

Reportedly, almost 311 plant species are found to be grown in the Atanasovsko Lake lagoon, out of which the Marsh samphire, reed, vicia and sea wormwood are a few to name

Which part of the brain consists of two large hemispheres, which are divided into smaller areas known as lobes?
vampirchik [111]

Answer:

The answer is the cerebrum.

Explanation:

The brain consists of the following parts; the cerebrum, cerebellum and the brainstem.

The cerebrum is the largest part of the brain located in front. It has two large hemispheres joined by the corpus callosum. The cerebrum has four lobes including frontal, parietal, temporal, and occipital lobes. Functions include: initiation and coordination of movement, memory, touch, hearing etc

The brainstem is composed of the midbrain, the pons, and the medulla. Controls involuntary muscle movements, cardiac function, sneezing etc.

The cerebellum located at the back of the head has two hemispheres. It is controls voluntary muscle movement, posture, balance and equilibrium.

What would be the pros and cons of using a gene drive in mosquitos? Would it be appropriate to use this technology to wipe out m
Vikki [24]

Gene drives is a powerful genetic engineering technology that may help to eradicate diseases transmitted by mosquitoes but it may also be harmful and cause the extinction of natural populations.

<h3>What are Gene drives?</h3>

Gene drives refer to a genetic engineering strategy based on genome editing (e.g., CRISPR-Cas9) that allows to produce a bias in the inheritance patterns of natural populations.

Gene drives modify normal inheritance to increase the selection coefficient of genetically engineered individuals, which may result in an advantage to control a vector population.

In conclusion, gene drives is a powerful genetic engineering technology that may help to eradicate diseases transmitted by mosquitoes but it may also be harmful and cause the extinction of natural populations.

Describe the vascular system of plants. Include brief descriptions of the characteristics and function of xylem and phloem.
solong [7]

Answer:

The vascular tissue of the plants distributes water and nutrients, which guarantees a constant growth. Each newly formed cell needs to become the corresponding cell type in vascular tissue.

Explanation:

Like animals, plants need water and nutrients. While animals use a circulatory and digestive system to obtain and distribute nutrients, plants use a vascular system. This system absorbs water, vitamins and minerals from the soil and then transmits energy in the form of carbohydrates to the roots. The main components of the vascular system are the xylem and the phloem.

<u>Xylem</u> is a complex tissue formed by several cell types. Its function is the conduction of water and minerals from the root to the leaves. Among the cells that form this complex tissue differ:

- Conductive cells or tracheal elements: they are dead elements at maturity, they serve for vertical conduction and support

- Vessel members are observed in Angiosperms, the largest plant group with the most recent evolution; They are short, wide cells with thick secondary walls, they differ from tracheids because they are perforated elements.

- Storage elements: parenchymal cells, thick walls, secondary, can present crystals and other cellular contents.

- Support elements: fibers in the Angiosperms and fibrotracheids in Gymnosperms, elements of intermediate characters between the fibers and the tracheids.

<u> Phloem</u> cells conduct food (photosynthesis produced by photosynthesis) from the leaves to the rest of the plant. They are living cells at maturity and in histological preparations colored with Astrablue take the color blue. Phloem cells are located outside the xylem.

The sieve elements of this tissue are: the sieve cells in the Gymnosperms and the members of sieve tubes with their respective accompanying cells in the Angiosperms. The accompanying cells retain their nuclei and control the neighboring sieve tubes. Dissolved food, such as sucrose, circulates through the screened areas that connect these cells to each other.

Being a complex tissue, it also has parenchymal cells for storage and fibers and sclereids as a support.
