Polar.
Polar means that it has a negative pole and a positive pole
Masteriza [31]3 years ago

Polar molecules have a positive and a negative area.

Explanation:

Polar molecules contain polar bonds because of the difference in electronegativity between the arms that are bonded. These molecules are net dipole because of opposing charges.  

An example of a polar molecule is water. It has both positive and negative charges on each side. The dipole in water does not cancel. Thus, making water like a net dipole molecule. Because of the polar nature of water, other polar molecules dissolve in water.

WILL CROWN BRAINLIEST why are the models of solar systems that you can purchase in stores not to scale?

Answer:

To put it simply, the models need to be smaller to fit on the Earth. If, the model was to scale, we'd risk getting crushed.

Within a gymnosperm megasporangium, which of the following developmental sequences is correct, assuming fertilization occurs? Gr
yan [13]

Within a gymnosperm megasporangium, the following developmental sequences that are correct, assuming fertilization occurs is: megaspore, female gametophyte, egg cell, sporophyte embryo. The last Option (Option D) is correct.

In gymnosperm megasporangium, the meiotic division produces four haploid megaspores from a single cell, three of which generally degenerate. The female gametophyte is formed by mitosis from the surviving megaspore.

Prior to fertilization, the male mature gametophyte needs to be transferred to the female gametophyte for fertilization to take place.

When the nuclei of the sperm encounter the nucleus of the egg cell in gymnosperms, it fuses with the egg nucleus to produce a diploid zygote.

Mitosis occurs in the fertilized egg to initiate the growth of a new sporophyte generation (the multicellular embryo of the seed.)

Therefore, we can conclude that we've understood the mechanism of developmental sequence in the gymnosperm megasporangium.

Arteries: any of the muscular-walled tubes forming part of the circulation system by which blood (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body.

Capillaries: any of the fine branching blood vessels that form a network between the arterioles and venules.

Veins: any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.

They are all similar because not only are they all connected to the heart, but they transfer blood and nutrients all around the body. They are different by where they are located and how effective their function is.

Science <br><br> Myth: Tigers and goldfish are not related.
DerKrebs [107]

Answer:

Although they are not closely related, as vertebrate animals, they share some characteristics and belong to the same Phylum.

Explanation:

Tigers and goldfish belong to different Classes. Tigers (<em>Panthera tigris</em>) belong to the Class Mammalia, while goldfish (<em>Carassius auratus</em>) belong to the Class Actinopterygii. However, they both belong to the Phylum Chordata.

Chordates share particular characteristics, such as a dorsal neural tube, a notochord, a bilateral symmetry, circulatory system, amongst other features. They are divided into different groups of vertebrates as well: mammals, birds, amphibians, reptiles, and fish. And, according to evolutionionary studies, over 300 million years ago, the first vertebrates that lived on land (amphibians) evolved from a lobe-finned fish species, which eventually led to the evolution of mammals that adapted to terrestrial environments.

Therefore, even though goldfish and tigers may seem completely different, they share similar characteristics. Plus, they are vertebrates that belong to the same phylum.
