Explain the connections among air pressure, temperature, humidity, and fronts.
Air mass is a large body of air that exhibits uniform temperature and moisture characteristics and helps to determine the weather within an area. Warm air masses tend to form over oceans in warm-temperature regions of the tropics and sub-tropics, while cold air masses tend to form over land in cold-weather regions nearer the poles. The cold air masses that form at the poles move toward the equator, while the warm air masses that form at the equator move toward the poles. These air masses can undergo gradual, but significant, changes as they pass over warmer or colder land surfaces encountering different types of air. These boundary lines are called front.

When will a dominant trait show its effect?
a
A) When two recessive genes for a trait are present.
B) Even if no dominant genes for that trait are present
C) In the presence of one dominant gene
D) Only if the mother has the trait.
When will a dominant trait show its effect in the presence of one dominant gene.
This goes to say that a dominant trait will show its effect even when individual only has one copy of the allele.
Why are the spores produced on the underside of the fronds?.
Explanation:
Each sporangium is a capsule that contains spores. They are usually aggregated into clusters called sori. The position and arrangement of the sporangia are very important for the identification of ferns. Fronds that have sporangia on their underside are fertile, and those that don't are sterile Ferns don't have seeds; they have spores. The spores are usually on the underside of the fronds. To reproduce, the fern releases the spores into the air. The spores don't grow into new ferns.
Sporangiums are spore-containing capsules. They form sori clusters. Ferns are identified by their sporangia position and arrangement. Fertile fronds have sporangia, whereas sterile ones don't.
What are fern fronds?Each sporangium is a spore-filled capsule. Typically, they are gathered into sori, or clusters. For the purpose of identifying ferns, the placement and arrangement of the sporangia is crucial. When a frond has sporangia on the underside, it is fertile; otherwise, it is sterile. Ferns produce spores rather than seeds. Usually, the underside of the fronds is where the spores are found. The fern disperses the spores into the atmosphere to reproduce.
Pteridophytes, including ferns, originated before flowering plants. They reproduce using spores rather than seeds. These spores mature and are then ejected from the capsule, where they germinate to become prothallus, a gametophyte that produces gametes.

Coastal regions experience moderate temperatures because winds prevent extreme temperatures in these regions. Which direction of wind makes these moderate temperatures possible?.
Answer:
b. from the ocean to the land
The direction of the wind that makes the moderate temperature in the coastal regions is from the sea to the land during the day, and from land to the sea during the night.
What do you mean by Coastal regions?The coastal regions may be defined as the area of land that borders the water bodies such as the sea.
The temperature of the coastal regions always remains moderate. This is because of the direction of the wind. The direction of the wind may change during the day as well as the nighttime.
Therefore, the direction of the wind that makes the moderate temperature in the coastal regions is from the sea to the land during the day, and from land to the sea during the night.

7. What causes greenhouse gasses to absorb heat when gasses like oxygen do not?
Answer:
Hope the below helps!
Explanation:
Greenhouse gases (such as methane, carbon dioxide etc) have lots of vibrating particles. These molecules eventually release radiation, which travels up Earth's atmosphere (because warm air rises), is trapped and adds to the greenhouse gas effect.
Oxygen and nitrogen don't interfere with infrared waves in the atmosphere. That's because molecules are picky about the range of wavelengths that they interact with.
I have attached a diagram that shows the greenhouse effect. It might help to visualise this.
Answer:
This is due to the Greenhouse Effect.
Explanation:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and some is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.As the heat makes its way through the atmosphere and back out to space, greenhouse gases absorb much of it.
Why do greenhouse gases absorb heat?
Greenhouse gases are more complex than other gas molecules in the atmosphere, with a structure that can absorb heat. They radiate the heat back to the Earth's surface, to another greenhouse gas molecule, or out to space. Here are several different types of greenhouse gases. The major ones are carbon dioxide, water vapor, methane, and nitrous oxide. These gas molecules all are made of three or more atoms compared to oxygen which only has 2 atoms. I hope this helps you.

Hypothesize the importance of language to the early modern humans and how it might have contributed to their success.
Answer:
Human language is unique among all forms of animal communication. It is unlikely that any other species, including our close genetic cousins the Neanderthals, ever had language, and so-called sign ‘language’ in Great Apes is nothing like human language. Language evolution shares many features with biological evolution, and this has made it useful for tracing recent human history and for studying how culture evolves among groups of people with related languages. A case can be made that language has played a more important role in our species’ recent (circa last 200,000 years) evolution than have our genes.

can an unfertilized egg develop into a human
Answer:
it's not possible till now bio science
An unfertilized egg cannot develop into a human.
WHAT IS FERTILIZATION?Fertilization is the process by which the sperm of a male organism fuses with the egg of a female organism to form a zygote, which then develops into a whole organism.
This suggests that to develop into a full grown organism, it takes an egg to be fertilized by a sperm.
Therefore, an unfertilized egg cannot develop into a human.

Q - Describe the Mitoses with the help of diagram. write its different phares and explain them.
Answer:
Mitosis is a type of cell division in which single haploid cell (n) or diploid cell (2n) divides into two haploid or diploid daughter cells that are same as the parent.
Mitosis occurs in somatic cells of plants and animals. In this cell division, the two daughter cells have the same number of chromosomes as that in the parent cells.
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase.
1.Prophase:-
It is the first visible stage in karyokinesis. The chromosomes appear as long coiled threads called chromatids. The chromatin becomes shorter, thicker and visible due to the condensation of DNA. The chromatins are now called chromosomes. Stainability of nucleus increase. Each chromosome starts to splits longitudinally into two sister chromatids. These sister chromatids are attached to each other at the centromere. The nuclear membrane and nucleolus start to disappear and by the end, it will be completely disappeared.
ii. Metaphase:-
Nuclear membrane and nucleolus completely disappears and simultaneously appearance of spindle fibers. Spindle fibers are attached to the centromere of a chromosome. The chromosomes are arranged on the equatorial plane. The process of gathering of chromosomes in equator is called congressional and plate formed is called metaphasic plate.
iii. Anaphase:-
The centromere of each chromosome splits into two sister chromatids and forms two daughter chromosomes. The daughter chromosomes are pulled towards the poles due to the contraction of spindle fibres and stretching of interzonal fibers. During polar movement, the chromosomes show different shapes i.e. J, U, V, L or I shaped in appearance. At the end of anaphase, each pole will get one set of daughter chromosomes. It is the shortest phase and is also known as a migratory phase.
iv. Telophase:- The daughter chromosomes reach respective poles and uncoil and become thin, long and visible. The spindle fibres start disappearing and finally disappear. The nuclear membrane and the nucleolus reappear.
Two nuclei are formed at the end of telophase. Both the nuclei have the same number of chromosome as the parent cell. It is the last visible stage of karyokinetic and is also known as reorganization phase.
It is followed by cytokines or division of cytoplasm.
