Animals with deuterostome development, bilateral symmetry as larvae, and five-part radial symmetry as adults are called?
Animals with deuterostome development, bilateral symmetry as larvae, and five-part radial symmetry as adults are called Echinoderms.
An echinoderm is any member of the phylum Echinodermata. The adults are recognizable by way of their (generally five-factor) radial symmetry, and encompass starfish, brittle stars, sea urchins, sand dollars, and sea cucumbers, in addition to the ocean lilies or "stone lilies".
Person echinoderms are found on the sea mattress at every ocean depth, from the intertidal quarter to the abyssal zone. The phylum incorporates about 7,000 dwelling species, making it the second-biggest grouping of deuterostomes, after the chordates. Echinoderms are the biggest completely marine phylum. The primary definitive echinoderms seemed close to the beginning of the Cambrian.
The echinoderms are critical both ecologically and geologically. Ecologically, there are few other groupings so plentiful inside the biotic desert of the deep sea, as well as shallower oceans. Most echinoderms are capable of reproducing asexually and regenerating tissue, organs, and limbs; in a few cases, they are able to undergo entire regeneration from a single limb.

3. Explain how mitosis results in genetically identical cells, using the terms chromosome, chromatid, and chromatin
What is the relationship between chromatin and chromosomes during mitosis?
Chromatin condensation causes the development of metaphase chromosomes, which are made up of two identical sister chromatids, as the cell enters mitosis. The centromere, which is a congested chromosomal area, is what holds these sister chromatids together.How do chromosomes duplicate during mitosis?
During telophase, the newly separated chromosomes reach the mitotic spindle and a nuclear membrane forms around each set of chromosomes, thus creating two separate nuclei inside the same cell.

The main dietary factor associated with elevated blood cholesterol is?
The main dietary factor associated with elevated blood cholesterol is saturated fat.
What about saturated fat?Because they increase the amount of LDL cholesterol in our blood, saturated fats, sometimes known as "bad fats," increase the risk of cardiovascular disorders (including heart disease and stroke). Cholesterol that is circulated in the blood. The majority of this cholesterol is produced by the body, however some is also absorbed from the meals you eat. Even if they include fat, foods derived from plants never contain cholesterol.Only foods from animals do. Low density lipoproteins are able to transport cholesterol. Dietary fat, particularly saturated and trans fats, may increase LDL and total cholesterol levels in the blood. Blood cholesterol levels may be lowered by substituting polyunsaturated and monounsaturated fats, particularly olive and canola oil, for some saturated fats.When we consume too much saturated fat, the receptors stop functioning as effectively, and blood cholesterol levels rise.Learn more about saturated fat here:

What is the function of the sporangium? question 11 options: a) passes characteristics from one generation to the next b) forms haploid cells through mitosis c) protects the mature gametes d) protects the developing mother spore cells
Answer:
D) Protects the developing mother spore cells
Explanation:
A structure called a sporangium is found in some plants and other creatures and is responsible for producing and storing spores. Spores, which are haploid structures made by organisms, aid in the germination and formation of new organisms.
A structure called a sporangium is found in some plants and other creatures and is responsible for producing and storing spores. Spores, haploid structures produced by organisms, aid in germination and the development of new species. They assist in the process of reproduction, in other words. What does it actually imply that they are haploid, though? Simply said, it indicates that there are just half the chromosomes needed to create a complete diploid creature. The sporangia can divide through mitosis, or cell division, to manufacture and release spores.
A single, potentially complex morphologically produced sporangium is produced by an unbranched sporophyte in mosses, liverworts, and hornworts. The majority of ferns, many lycophytes, and non-vascular plants are homosporous (only one kind of spore is produced). Some ferns, the majority of lycophytes, and some bryophytes are heterosporous (two kinds of spores are produced). These plants generate gametophytes that are functionally male or female, respectively, by the development of microspores and megaspores. Occasionally, two types of spores are generated in the same sporangium and may even form a spore tetrad together.
Microsporangia and megasporangia, two different types of sporangia, are present in the majority of heterosporous plants. All seed plants, as well as a few ferns (Salviniaceae and Marsileaceae), some lycophytes (genera Selaginella and Isoetes, as well as the extinct lepidodendrids), are heterosporous with two types of sporangia.
Sporangia can grow near the terminals of stems, along their sides, or in close proximity to leaves. In ferns, sporangia are often located on the abaxial surface of the leaf, or the underside, where they are tightly grouped into clusters called sori. An indusium, a type of structure, could be present across Sori. The sporangia of certain ferns are dispersed along with the shortened leaf segments or along (or just in from) the leaf edge.
The sporangium has an indirect involvement in sexual reproduction and an active part in asexual reproduction in several phyla of fungus. The sporangium, which has haploid nuclei and cytoplasm, develops on the sporangiophore. Each haploid nucleus and cytoplasm are encased in a hard outer membrane as the spores develop in the sporangiophore. These spores spread by wind during asexual reproduction and develop into haploid hyphae.
Although sexual reproduction in fungus differs between phyla, the sporangium indirectly contributes to sexual reproduction in some fungi. When two haploid hyphae from different individuals combine to produce a zygosporangium in response to adverse circumstances, sexual reproduction takes place in Zygomycota. The zygosporangium's haploid nuclei subsequently combine to form diploid nuclei.
When the environment is more favorable, the zygosporangium germinates, goes through meiosis, and develops into a sporangium that releases spores.

What is the motion of horizontal and vertical air in a high-pressure anticyclone and in a low-pressure cyclone?Winds near the surface move across the isobars at an angle when the frictional force is combined with the pressure gradient force and the apparent force of the Coriolis effect. Consequently, the air spirals and converges as it advances in the direction of low pressure. A cyclone sometimes referred to as a low-pressure system, is created by this spiraling inward toward a center of low pressure. Convergence is the technical term for this inward spiraling action, which likewise raises the air at the center.
Air spirals downward and outward from an anticyclone, also known as a high-pressure system, in a high-pressure area. Divergence is the name for this spiraling outward motion. Cyclones rotate anticlockwise in the northern hemisphere and clockwise in the southern hemisphere.
