tRNA molecules physically link the mRNA message and the _______ it encodes for. The ribosome is made of proteins and _______
Answers
The tRNA molecules physically link the mRNA message and the amino acids it encodes for. The ribosome is made of proteins and rRNA (ribosomal RNA).
tRNA molecules play a crucial role in protein synthesis. They are responsible for carrying amino acids to the ribosome, where they are added to the growing polypeptide chain according to the mRNA template. The tRNA molecules have an anticodon sequence that is complementary to the codon sequence on the mRNA. This complementary base pairing ensures that the correct amino acid is added to the growing chain. The ribosome, on the other hand, is made up of proteins and rRNA. The proteins provide structural support and enzymatic activity, while the rRNA molecules help in the decoding of the mRNA message and the formation of peptide bonds between amino acids. Together, tRNA molecules and ribosomes ensure the accurate translation of the genetic code into proteins.

What psychologist proposed that humans, along with members of other species, have a fighting instinct, which in earlier times ensured protection of food supplies and weeded out the weaker of the species?
Answers
The psychologist who proposed that humans have a fighting instinct is Konrad Lorenz, who believed it ensured protection of resources and survival of the fittest.
Konrad Lorenz, an Austrian zoologist and ethologist, suggested that humans and other species possess an innate fighting instinct. He argued that this instinct played a crucial role in our ancestors' survival by enabling them to protect their food supplies and territory.
Additionally, it served as a natural selection mechanism, ensuring only the strongest individuals would survive and reproduce. This instinct, according to Lorenz, has persisted into modern times and still influences human behavior.

why do plants cell contain cell wall but animal cells does not? i need an easy explanation
Answers
Answer:
Hi
Explanation:
A plant cell needs a cell wall because they need a rigid structure to grow up and out. In addition, a plant cell wall makes sure that the cell does not burst as water flows in-- a concept called "internal turgor pressure". It helps to maintain the shape and osmolarity of the cells. Animal cells don't need to do that.
Answer:
Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out so that they get lots of sunlight for making their food. Animal cells have flexible cell membranes. So animal cells can have various shapes, but plant cells cannot and they have to take the shape of their cell walls.

Answers
When the genetic counsellor explains the structural changes in chromosomes that result from breakage and rearrangement of chromosome parts, the pattern that occurs when there are simultaneous breaks in two chromosomes, from different pairs, with exchange of chromosome parts is translocation.
When two distinct chromosomes experience a double break and exchange fragments, translocations—structural chromosome abnormalities—occur. There are two different forms of translocations: reciprocal and Robertsonian.
Breaking and exchanging distal portions between nonhomologous chromosomes results in reciprocal translocations. In both the general population and neonates, balanced reciprocal translocations occur about 0.14% of the time. When two acrocentric chromosomes (chromosomes 13, 14, 15, 21, and 22) fuse and lose their short arms, a translocation known as a Robertsonian translocation results. Their prevalence in the population is 0.12%, and the fusion of chromosomes 13 and 14 is the most frequent variant.
When a segment of one chromosome separates and joins another chromosome, the process is known as a translocation. If there is neither genetic material gain nor loss in the cell, this form of rearrangement is referred to as balanced. A translocation is referred to as imbalanced if genetic material is gained or lost.

The intensity of sunlight on Earth is affected by
A.) the mass of Earth
B.) the speed of Earth
C.) the number of rotations of Earth
D.) the curved surface of Earth
Answers
Answer:
The correct answer is D.) the curved surface of Earth.
Explanation:
The intensity of sunlight on Earth is affected by the curved surface of Earth, which causes the sunlight to spread out over a larger area. As a result, the intensity of sunlight is less at any given point on Earth's surface than it would be if Earth had a flat surface. This also explains why the poles receive less sunlight than the equator, as sunlight is spread out over a larger area near the poles due to the curvature of the Earth.
Factors such as the mass of Earth, the speed of Earth, and the number of rotations of Earth do not directly affect the intensity of sunlight on Earth.

Lower, Lower
Lower, Higher
Answers
The higher the amplitude (height of a wave), the greater the energy the wave carries.The relationship between amplitude and energy in a wave can be described as follows: the higher the amplitude, the greater the energy the wave carries.
1. Amplitude refers to the maximum displacement or distance moved by a point on a wave from its equilibrium position. In simpler terms, it represents the height of a wave.
2. Energy, in the context of waves, is the amount of work that can be done by the wave as it moves through a medium, such as air or water.
3. The energy of a wave is directly related to its amplitude. When the amplitude of a wave is higher, it indicates that the wave is carrying more energy.
4. Therefore, when comparing two waves, the one with a higher amplitude will have a greater energy, and the one with a lower amplitude will have less energy.

Blank is the transfer of energy by a wave off a surface
Answers
Reflection is the transfer of energy by a wave off a surface.
Reflection occurs when a wave encounters a surface and bounces back, transferring energy in the process. When a wave strikes a surface, it interacts with the molecules or particles of the medium or object it encounters. Depending on the properties of the surface and the nature of the wave, different outcomes can arise.
During reflection, the wave energy is redirected back into the original medium, with the angle of incidence being equal to the angle of reflection. This phenomenon can be observed in various types of waves, such as light waves, sound waves, and water waves. The reflection of waves plays a significant role in our daily experiences, from seeing our reflection in a mirror to hearing an echo in a large empty room.
The process of reflection allows waves to propagate and travel through space or a medium by bouncing off surfaces. It is an essential mechanism for the transmission and interaction of waves and contributes to our understanding of how waves behave and interact with their surroundings.

calculate the ni for the three strongest of the lines in the hydrogen spectrum
Answers
The ni values for the three strongest lines in the hydrogen spectrum are Lyman series: ni = 2, 3, 4, ..., Balmer series: ni = 3, 4, 5, ..., Paschen series: ni = 4, 5, 6, ...
The ni values represent the principal quantum numbers for the energy levels of the hydrogen atom. The three strongest lines in the hydrogen spectrum correspond to the transitions between the higher energy levels (nf) and the lowest energy level (n=1). To calculate the ni values, we need to determine the principal quantum numbers (ni) for these transitions.
The three strongest lines in the hydrogen spectrum are:
Lyman series (Ultraviolet region): nf = 1
This corresponds to transitions from higher energy levels (ni) to the ground state (n=1).
Therefore, ni = 2, 3, 4, ...
Balmer series (Visible region): nf = 2
This corresponds to transitions from higher energy levels (ni) to the first excited state (n=2).
Therefore, ni = 3, 4, 5, ...
Paschen series (Infrared region): nf = 3
This corresponds to transitions from higher energy levels (ni) to the second excited state (n=3).
Therefore, ni = 4, 5, 6, ...
Note that the ni values represent the starting energy levels (higher energy levels) for the transitions. The actual wavelength or frequency of the lines in the hydrogen spectrum is determined by the difference in energy between the initial (higher energy) and final (n=1) states.
Therefore, the ni values for the three strongest lines in the hydrogen spectrum are:
Lyman series: ni = 2, 3, 4, ...
Balmer series: ni = 3, 4, 5, ...

The thyroid, or thyroid organ, is an endocrine organ in vertebrates. In people, it is in the neck and comprises of two associated curves. A thin band of tissue known as the isthmus connects the lower two-thirds of the lobes. The thyroid gland is a butterfly-shaped organ beneath the Adam's apple in the neck. The spherical thyroid follicle, which is lined with follicular cells (thyrocytes) and occasionally parafollicular cells and has a colloid-filled lumen, is the thyroid gland's functional unit at a microscopic level.
Three hormones are released by the thyroid gland: the two thyroid chemicals - triiodothyronine (T3) and thyroxine (T4) - and a peptide chemical, calcitonin. The metabolic rate, protein synthesis, and growth and development of children are all influenced by thyroid hormones. Calcium homeostasis is affected by calcitonin. The anterior pituitary gland secretes thyroid-stimulating hormone (TSH), which controls the two thyroid hormones. The hypothalamus makes thyrotropin-releasing hormone (TRH), which controls TSH.
