A log has a density of .8 g/cm³. This log will _______ in freshwater, which has a density of 1.0 g/cm³ .
m_a_m_a [10]
The log will float on the water because his density is lower than the liquid, so it will stay at the top due to Archimedes' principle.

<span>Archimedes' principle is a physical law that describes the upward force (the vertical thrust) experienced by any body immersed in a fluid (liquid or gas). This force is strongly related to the density of both the fluid and the body.
</span>
You can try the experience at home, by using an object that has a lower density than the water like the sunflower oil, you will see that it will stay at the top of the water too.

What is the name of the groove that forms in the middle of a dividing plant cell
mrs_skeptik [129]

Plants have cell walls, so cytokinesis cannot go on with a cleavage furrow, but instead, a cell plate  forms across the cell in the location of the metaphase plate.

There is no distinct groove along the cell plate as the cell divides because of the rigid nature of the cell plate or new cell wall.

A plant cell divides differently from an animal cell which forms a clear cleavage furrow because it only has a flexible cell membrane and not a rigid cell wall like plants.

The cell plate in plant cells is formed by membrane bound vesicles which migrate to the center of the cell where the metaphase plate used to be and fuse together to form a cell plate.

Explain the relationship among
Iteru [2.4K]

Answer:

There is an important relationship among  homeostasis, defective mitochondria, and the  symptoms caused by LHON.

Explanation:

There is a great relationship among  homeostasis, defective mitochondria and the  symptoms caused by LHON because defective mitochondria disturbs the homeostasis in the body. If mitochondria works properly, homeostasis will be maintained whereas if there is any defect occurs in the mitochondria then the whole homeostasis will be adversely affected because mitochondria is the powerhouse of the cell responsible for the production of energy for the cell. Symptoms occurs due to Leber's hereditary optic neuropathy (LHON) also effected the state of equilibrium in the body.

What is the function of the sporangium? question 11 options: a) passes characteristics from one generation to the next b) forms
Ivenika [448]

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.
