What are sex chromosomes? What is the sex chromosome combination for human males and females?

Answers

Answer 1

Answer:

(Wow! Weird how this pooped up, I just finished this biology lesson.)

Sex chromosomes are the gene that decides on our gender. The males have X and Y sex chromosomes (XY). Females have only two  X sex chromosomes (XX).

More info: Because males have both X and Y sex chromosomes, their genes decide the offspring's gender.

Answer 2

Answer:

The sex chromosomes are referred to as X and Y, and their combination determines a person's sex. Typically, human females have two X chromosomes while males possess an XY pairing. This XY sex-determination system is found in most mammals as well as some reptiles and plants

Which principle states that two species in the same habitat cannot have the same niche?
niche exclusion principle
competitive exclusion principle
habitat exclusion principle
population exclusion principle

Answers

Answer:

competitive

Explanation:

example 1: two male bucks cannot inhabit the same habitat or area because one needs all the females or pride for itself so it chases away the others

The competitive exclusion principle explains that two species occupying the same niche cannot coexist in the long term since competition is created between them for resources.

What is the competitive exclusion principle?

It is a phenomenon that refers to the competition that one species has with another and the dependence of one organism to develop in terms of the other organism.

In competitive exclusion, one species is displaced by another when their niches overlap and compete for the same resources.

Therefore, we can conclude that the competitive exclusion principle establishes that two species that have the same ecological needs cannot live together since they create competition between them for resources.

Emission lines are lines that are made when wavelengths of light are given off by cooling gases.
O True
O False

Answers

Answer:

Its FALSE on edge

Explanation:

When cooling gases emit light wavelengths, lines known as emission lines are created. The first people to notice constellations were the ancient Romans and Greeks.

What Emission lines that are made when wavelengths light?

Monochromatic light has a single wavelength and is generated by lasers, which exploit transitions between two atomic energy levels to generate light with an extremely restricted range of wavelengths.

While emission lines refer to the lines of light produced by burning hot gas, absorption lines refer to the tendency of cool ambient gas to absorb the same lines of light.

Some light at specific wavelengths is scattered when it travels through the atmosphere's gas, producing darker bands.

Therefore, It is false that Emission lines are lines that are made when wavelengths of light are given off by cooling gases.

Please do have a great rest of your day!

The cycle that powers the ocean currents, weather, and tectonic plates it called convection current​. The correct option is d.

What is convection current?

Convection is the spontaneous flow of a single or multiphase fluid caused by the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity.

Convection currents are generated by radioactive decay in the core as heat rises and falls within the mantle. The plates are moved by convection currents.

Plates move apart where convection currents diverge near the Earth's crust. Plates move towards each other where convection currents converge.

Convection currents propel Earth's rigid tectonic plates through the planet's fluid molten mantle.

Tectonic plates move away from each other in places where convection currents rise up towards the crust's surface, a process known as seafloor spreading.

Thus, the correct option is d.
