Answer:

nucleic acids.

Explanation:

The fusion of the sperm with the egg results in the formation of a zygote that develops into a new offspring. Twins refers to the two offspring which are a result of the same pregnancy. They are of two types. Monozygotic twins are a result of the single zygote (formed by the fusion of one egg with a single sperm) spiltting into two embryos forming the identical twins. Dizygotic twins are a result of two eggs fertilized with two different sperms forming the fraternal twins.

Identical twins are genetically simliar. The genetic material is derived from the same embryo and thus, the DNA of the identical twins are nearly identical. The spilitting of the embryo formed results in the separation of the same genetic material or identical DNA getting incorporated into the twins making them look alike in majority of the cases.

An earthquake has a high magnitude but a low intensity. Which statement best explains this?(1 point)
Lera25 [3.4K]

Answer:

Magnitude and Intensity measure different characteristics of earthquakes. Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location.

Why are so many eggs produced by invertebrates?
klasskru [66]
An egg is the organic vessel containing the zygote in which an animal embryo develops until it can survive on its own, at which point the animal hatches. An egg results from fertilization of an ovum. Most arthropods, vertebrates, and mollusks lay eggs, although some do not, such as scorpions and most mammals.

Reptile eggs, bird eggs, and monotreme eggs are laid out of water, and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a favorable temperature range (warm) while the embryo grows. When the embryo is adequately developed it hatches, i.e. breaks out of the egg's shell. Some embryos have a temporary egg tooth with which to crack, pip, or break the eggshell or covering.

The influx of positive charges that makes the membrane potential more positive is?
Sunny_sXe [5.5K]

The influx of positive charges makes the membrane potential more positive and is known as depolarization.

<h3>What makes the membrane more positive charge ?</h3>

The membrane potential normally becomes more positive in response to neurotransmitters that open Na+ channels, more negatively in response to those that open K+ channels, and vice versa in response to neurotransmitters that inhibit these channels.

<h3>What does polarization mean?</h3>

The orientation dispersion of the electromagnetic waves that make up light beams is referred to as polarization. Unpolarized (uniformly mixed orientations), linearly polarized (fixed orientations), and circularly polarized are some of the different polarization states that light can take on (rotating field about the line of sight).

<h3>How membrane is affected by polarization and depolarization?</h3>

At a specific location on the neuron's membrane, hyperpolarization occurs when the membrane potential increases, and depolarization occurs when the membrane potential decreases (more positive).
