Where do cold fronts form and what type of weather is formed?
Answer:
Cold fronts form when a cooler air mass moves into an area of warmer air in the wake of a developing extratropical cyclone. The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation
Match the following DNA strand to its complementary strand of RNA
TTA - CAA - ACC - ATA
Question options:
AAU - GUU - UGG - UAU
AAT - GTT - TGG - TAT
AAU - CTT - TGG - TAT
ATG - CCG - AAT - TCG
Answer:
AAU - GUU - UGG - UAU
Explanation:
Thymine is present in RNA strands as the base Uracil, making there an inability to have Thymine in an RNA strand.
Hope this helped :)
Answer:
The first option: AAU - GUU - UGG - UAU
Explanation:
RNA has the nitrogenous bases adenine (A), uracil (U), guanine (G), and cytosine (C). A pairs with U while G pairs with C. The thymine (T) from the DNA must be complemented by the adenine (A) from the RNA, too.
Knowing this, the complementary strand of RNA would be the first option. Another way of finding the answer would be noticing that all the other options have thymine (T), which is a nitrogenous base RNA does not have.
Which scenario describes an interaction between two of Earth’s spheres?
1. Water flows from a stream to a lake.
2. Gravity moves rocks to another location.
3. Lions use energy to catch other animals for food.
4. Bears dig big holes in the ground to protect their young.
Answer: D
Explanation:
Bears are living so they are biosphere while the rocks they and Are interacting with are geosphere so it’s biosphere interacting with geosphere hence, D because two spheres interact and gravity isn’t a sphere water is interacting with hydrosphere which arent different so tis basically hydrosphere with hydro and lions use energy is just biosphere with biosphere and last one makes sense cuz it’s two different bio and geo!
Which of the following statements correctly compares terrestrial and Jovian planets?
А
Jovian planets are generally warmer due to their proximity
to the Sun.
B
Terrestrial planets have longer
periods of revolution.
С
Terrestrial planets are denser due to their rocky composition.
D
Jovian planets are smaller in diameter.
Answer: C
Explanation: terrestrial planets are denser then the Jovian (Outer) planets since they are mostly made of rocky material, while the Jovian planets are gaseous.
Saturn, for example, would theoretically be able to float in water due to its low average density.

which level of tornado tornados causes the greatest damage?
A: EF0
B: EF1
C:EF5
D:EF10
Answer:
The correct answer is C:EF5.
Explanation:
The Tornado is a meteorological phenomenon that consists of a whirlwind of wind produced as a result of an air rotation of great intensity and of little horizontal extension, which extends from the base of a mother cloud. The Fujita-Pearson scale and the so-called Enhanced Fujita Scale classify tornadoes according to the damage caused. The Enhanced Scale (EF) was a refinement of the old Fujita scale, using wind estimates and better damage descriptions; however, it was designed so that a tornado rated on the Fujita scale would receive the same numerical rank, and was implemented beginning in the United States in 2007. An EF0 tornado, the weakest on the scale, possibly damages trees but not structures, as long as that an EF5 tornado, the strongest, it can cause incredible devastation; it can rip buildings off their foundations, exposing them and even deform skyscrapers. The wind speed in a tornado can reach 500 km / h.

How do tissues relate to the structure and function of organs?
Answer:
In biology, tissue is a cellular organizational level between cells and complete organs. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.
If a second cross is made using these offspring and results are ¾ short haired while ¼ are long haired can you now determine the exact genotypes of the parents and if so what are they?
Complete question:
In guinea pigs, the allele for short hair is dominant. All the guinea pigs are born short-haired. If a second cross is made using these offspring and results are 3⁄4 short-haired while 1⁄4 are long-haired can you now determine the exact genotypes of the parents and if so what are they?
Answer:
The exact genotype of both the F2 parents is Ss, heterozygous for the trait hair length.
Explanation:
Due to technical problems, you will find the complete answer and explanation in the attached files
How old do scientists believe was the earliest cell on earth?

how do enzymes affect activation energy in a chemical reaction
Answer:
Enzymes lower the activation energy that is needed, making reactions happen at a lower temperature that they could without the enzyme. This speeds up the rate of reaction.

TRUE OR FALSE
Once water seeps down under the ground, it stays there
forever.
Answer:
i Feel like its false but it could be true
Explanation:
As you know or dont, Water at very shallow depths might be just a few hours old; at moderate depth, it may be 100 years old; and at great depth or after having flowed long distances from places of entry, water may be several thousands of years old. As water seeps into the ground, some of it clings to particles of soil or to roots of plants just below the land surface. This moisture provides plants with the water they need to grow. Water not used by plants moves deeper into the ground. The water then fills the empty spaces and cracks above that layer

Explain why the size of a new moon would affect the appearance of a solar eclipse.
Answer:
A solar eclipse can occur only when new moon occurs close to one of the points (known as nodes) where the Moon's orbit crosses the ecliptic. ... Therefore, the Moon's apparent size varies with its distance from the Earth, and it is this effect that leads to the difference between total and annular eclipses.
A single cell of testis divides to produce:
a. 4 sperms.
b. 6 sperms.
c. 2 sperms.
d. a single sperm.
Answer:
Each primary spermatocytes goes through the first meiotic division, meiosis I, to produce two secondary spermatocytes, each with 23 chromosomes (haploid). Just prior to this division, the genetic material is replicated so that each chromosome consists of two strands, called chromatids, that are joined by a centromere.
Answer:
Assertion In the testis, spermatogenesis occurs in the seminiferous tubules and testosterone secretion takes place from the Sertoli cells. Reason Testosterone brings growth and maturation of secondary s3x organs and also the development of accessory s3x characters.
