How many nucleotides are there in 5 codons?
Who can help me
Answer:
15 because one codon has 3 nucleotides
Explanation:
If a sperm containing 46 chromosomes fused with an egg
containing 46 chromosomes, how many chromosomes would
the resulting fertilized egg contain?
Do you think this would create any problems in the developing
embryo?
Answer:
Explanation: yes would cause problems with the embryo because a sperm and egg have 23 chromosomes each half mom half dad.
The sperm cell and the egg cell contain 46 chromosomes each, 46 + 46 = 92; a developing embryo would not survive if it contained 92 chromosomes.
What is fertilization?This process results in the restoration of the diploid state, the formation of a zygote through the process of egg activation, and the beginning of a series of mitotic divisions that leads to cell differentiation and embryo development.
When a sperm and a female act during sexual contact, an egg is created and implanted in the female's uterus, resulting in fertilization. The sperm enters the fallopian tube, passes through the ovum's zona pellucida layer, and fuses with the egg to create the zygote (fertilized egg).
Therefore, 46 chromosomes are found in each sperm and egg cell, for a total of 92 chromosomes. An embryo would not survive if it had 92 chromosomes.

what property is the mineral in this image demonstrating?
a. magnetism
b. fluorescence
c. luster
d. streak
help me asap. pls.
When a particular wavelength of light, such as ultraviolet (UV) light, electron beams, or x-rays, are focused on a mineral, fluorescence takes place, hence option B is correct.
What is the property of minerals?Calcite, fluorite, and sodalite are among the more popular fluorescent minerals, however there are many more as well. When exposed to UV light, many gemstones, including diamonds, rubies, emeralds, amber, and opal, will glow.
This light stimulates the mineral's electrons, forcing them to momentarily move to a higher orbit.
Naturally, mine wastes and tailing heaps provide excellent locations for any mineral, including fluorescents.
Therefore, nearly everywhere that has a good assortment of white light minerals also has fluorescent minerals, hence option B is correct.

As a naturalist, you are responsible for training volunteers in the identification of the types of amphibians. The volunteers will use this information to correctly describe the animals to school groups that will visit your nature center. The training documentation for the volunteers lists important characteristics of the different groups of amphibians, but you notice that one of the items on the list is incorrect. Indicate which description is not correct.
A. Frogs, toads, and most salamanders have four legs whereas caecilians are legless.
B. While some frogs may advertise their distasteful nature by bright coloration, salamanders always have cryptic coloration.
C. Some adult salamanders retain larval characteristics such as external gills.
D. Most caecilians can be found burrowing in the soil of tropical forests.
Answer:
B. While some frogs may advertise their distasteful nature by bright coloration, salamanders always have cryptic coloration.
Explanation:
Amphibians are vertebrates which can live both on land and in water. they are cold-blooded and therefore, depend on warmth from sunlight to become warm and active. Their young live fully in water respire using gills. The adults have moist skins through which they respire and therefore, live in moist places or near water to keep their bodies from drying out. Many adult amphibians also have poison-producing glands in their skin to ward off predators. Poisonous amphibians usually display a warning coloration. . The species in this group include frogs, toads, salamanders, caecilians and newts.
Considering the above descriptions:
A. Frogs, toads, and most salamanders have four legs whereas caecilians are legless.
True: Caecilians are a group of limbless, wormlike or serpentine amphibians that mostly live in underground burrows or in substratum of shallow streams.
B. While some frogs may advertise their distasteful nature by bright coloration, salamanders always have cryptic coloration.
False: Some frogs such as poison frogs as well as some salamanders such as the California newt and the red eft which a brightly colored terrestrial juvenile form of the eastern newt is highly poisonous. advertise their distasteful nature by bright coloration.
C. Some adult salamanders retain larval characteristics such as external gills.
True: Some adult salamanders retain larval characteristics such as external gills. e.g. species such as the mudpuppy (Necturus maculosus) retain their gills throughout their lives.
D. Most caecilians can be found burrowing in the soil of tropical forests.
True: Caecilians are a group of limbless, wormlike or serpentine amphibians that mostly live in underground burrows or in substratum of shallow streams.

What factors play a role in how fast, far, or what direction DNA fragments travel for gel electrophoresis?
Explanation:
DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode, Shorter strands of DNA move more quickly through the gel than longer strands resulting the fragments being arranged in order of size.

What are the different types of leaves that plants have?
Answer:
There are two different types of leaves – simples leaves and compound leaves. The other types of leaves include acicular, linear, lanceolate, orbicular, elliptical, oblique, centric cordate, etc. They perform the function of photosynthesis and help in the removal of excess water from the aerial parts of the plant. The most obvious aspect to examine is the shape of the leaf. If it is an uninterrupted shape, it is simple. If the shape divides into smaller leaf sets the leaf is compound. Identifying plant leaves that are compound divides them into subsets.

Explain what happens to the incoming solar radiation on a cloudy day, and how this affects the temperature at Earth's surface.
Answer:
During the day, the earth is heated by the sun. If skies are clear, more heat reaches the earth's surface (as in the diagram below). This leads to warmer temperatures. However, if skies are cloudy, some of the sun's rays are reflected off the cloud droplets back into space.

Given is a strand of DNA, fill in the corresponding RNA strand and find which amino acids that strand codes for.
Please help!
Answer:
RNA: [tex]A-U-G-U-A-U-A-C-G-G-A-U-U-G-A[/tex]
Amino acids: Methionine, Tyrosine, Threonine, Aspartic Acid
Explanation:
1) First, transcribe the DNA to RNA. For each nitrogenous base (to put it simply, the letter) listed in the DNA strand, write the strand of RNA with the matching nitrogenous base. Remember that, when transcribing, the thymine (T) from DNA can pair with adenine (A) in the RNA, adenine (A) pairs with uracil (U), and cytosine (C) and guanine (G) always pair with another.
DNA: [tex]T-A-C-A-T-A-T-G-C-C-T-A-A-C-T[/tex]
RNA: [tex]A-U-G-U-A-U-A-C-G-G-A-U-U-G-A[/tex]
2) Next, to find the amino acids the strand codes for, read the nitrogenous bases in the RNA from left to right in groups of three, or codons. Then, using a codon chart, find which amino acid the group of three bases codes for. This gives the following answer below. (Remember that the codon UGA stops the translation and therefore does not code for an amino acid.)
Amino acids: Methionine, Tyrosine, Threonine, Aspartic Acid
Amino acids: Methionine, Tyrosine, Threonine, Aspartic Acid
What are amino acids?Amino acids are the building blocks of protein. Proteins are long chains of amino acids. Your body has thousands of different proteins that each have important jobs. Each protein has its own sequence of amino acids.
Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids.
The human body uses amino acids to make proteins to help the body: Break down food. Grow. Repair body tissue.

Can someone please do a summary on how wind works? 7-9 sentences please I will mark brainliest!
Answer:
Wind is the movement of air. It forms when air moves from areas of high-pressure to areas of low pressure. These pressure differences are caused by temperature differences on Earth's surface. The movement is a result of different places on Earth receiving different amounts of energy from the sun. Two types of winds are global and local. Global wind systems determine weather patterns for the entire planet. Local winds are sea and land breezes that occur due to uneven absorption of solar energy.
