What properties of photosynthetic pigments allow pigments to absorb light of only certain wavelengths? Select all that apply.
Light of any energy level can boost an electron of the pigment molecule to a higher energy level in order to be absorbed.
Only light with the correct wavelength to boost an electron of the pigment to a higher energy level is absorbed.
Some pigment molecules lack a light-trapping region.
All pigment molecules possess a light-trapping region with a special structure that allows electrons to move freely
between Its atoms.
Answers
The properties of photosynthetic pigments that allow pigments to absorb light of only certain wavelength is ; ( B and D )
Only light with the correct wavelength to boost an electron of the pigment to a higher energy level is absorbed.All pigment molecules possess a light-trapping region with a special structure that allows electrons to move freely between Its atoms.The Green pigment found in plants ( i.e. photosynthetic pigment ) that absorb light energy used by plants during photosynthesis is the chlorophyll. It absorbs light energy based on the wavelength of the visible light while reflecting visible green light due to its wavelength.
The reflection of the visible green light by the chlorophyll gives the plants leaves the green color it possesses.
Hence we can conclude that The property of photosynthetic pigments that allow pigments to absorb light of only certain wavelength is ; Only light with the correct wavelength to boost an electron of the pigment to a higher energy level is absorbed. and statement D.

El proceso da como resultado cuatro células hijas que son haploides, lo que significa que contienen la mitad del número de cromosomas de la célula madre diploide. La meiosis tiene similitudes y diferencias con la mitosis, que es un proceso de división celular en el que una célula madre produce dos células hijas idénticas. Espanol

Explanation:
Stella described protein synthesis as a process that makes the necessary proteins for the human body to function. She
explained the process in the following steps.
1. DNA is transcribed into mRNA.
2. Amino acids form a chain.
3. The amino acid chain is folded into a protein in the endoplasmic reticulum.
What step did Stella miss in her explanation?
(1 point)
O Polypeptide chains express gene traits.
O tRNA delivers the DNA to the ribosome.
hy
O DNA is replicated into two daughter cells.
O mRNA is translated into amino acids.
Answers
The step of protein synthesis missed by Stella would be the translation of mRNA into amino acids.
The process of protein synthesis can essentially be divided into 2, namely:
TranscriptionTranslationDuring transcription, genetic information on DNA is transcribed into mRNA. Once this is done, the genetic codes in mRNA are then translated to their respective amino acids and linked by peptide bonds.
The polypeptide bond undergoes further processing such as folding in the endoplasmic reticulum.
Thus, before amino acids can form a polypeptide chain, they must first be translated from genetic codes in mRNA.

the two proteins directly involved in muscle contraction are broadly called
Answers
The two proteins directly involved in muscle contraction are MYOSIN AND ACTIN. The interaction between these proteins is responsible for muscle contraction.
The sarcomere is the basic unit of muscle cells (myofibrils) that mediate muscle contraction both in skeletal and cardiac muscle tissue.
During muscle contraction, myosin and actin proteins slide past each other, thereby leading to sarcomere shortening.
The myosin protein binds to actin filaments and thus myosin acts as a motor protein that drives filament sliding.

The brain of mammals keeps track of the temperature of the skin and the blood so that they can regulate the cells and maintain homeostasis in the body relative to the outer environment.
What is the importance of homeostasis in the body?The body's homeostasis should always be maintained in order to keep the cells and organs active and able to perform their functions. Because the brain has different control centers, it keeps track of the skin and blood temperature because the brain can release different hormones depending on the situation. The lipid composition and arrangements of the cells change in the summer and the winter, and all these are possible due to the brain sending signals to cells.
Hence, the brain of mammals keeps track of the temperature of the skin and the blood so that it can regulate the cells and maintain homeostasis in the body relative to the outer environment.

Other useful elements for describing climate include the type and the timing of precipitation, amount of sunshine, average wind speeds and directions, number of days above freezing, weather extremes, and local geography.
Climate features also include windiness, humidity, cloud cover, atmospheric pressure, and fogginess. Latitude plays a huge factor in determining climate. Landscape can also help define regional climate. A region's elevation, proximity to the ocean or fresh water, and land-use patterns can all impact climate.
