Answer: A tRNA with the complementary anticodon is attracted to the ribosome and binds to this codon. The tRNA carries the next amino acid in the polypeptide chain. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids.

To see a general view of a microscope slide, use _____ power. If you need to see a more specific and detailed view, use _____ power.
Answer:
Low; high.
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
Basically, a microscope is used for viewing very little objects, microorganisms and cells found in living organisms such as humans, animals and plants.
The interchangeable lenses found in a microscope which are close to the specimen being observed are called objective lenses. These objective lenses comprises of low power objective and high power objective. To see a general view of a microscope slide, use low power. If you need to see a more specific and detailed view, use high power.
Hence, the field of view (FOV) is largely dependent on the objective lens being used, it is largest (general view) for low power and smallest (specific and detailed view) for high power.

what is the S.I unit of speed , time
Answer:
Second!
Explanation:
speed and velocity are both measured using the same units.The S.I unit of distance and displacement is the meter. The S.I unit of time is the second. The S.I unit of speed and velocity is the ratio of two-the meter per second!
I hope it's helpful!
Answer:
metre per second
Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour.

Which of the following patterns in the fossil record would be an example of an organism evolving through punctuated equilibrium?
A. dorsal fins appearing, disappearing, and reappearing in species of ancient aquatic reptiles, mammals, and fish
B. a species of flower changing in shape, followed by a change in the beak shape in its preferred species of pollinator
C. the shell shape of a species of snail remaining unchanged for millennia until it changes to an entirely different shape
D, whale species gradually changing from land-dwelling mammals that walked on four legs to marine mammals without legs
Whale species gradually changing from land-dwelling mammals that walk on four legs to marine mammals without legs would be an example of an organism evolving through punctuated equilibrium. So, the correct option is (D).
What is Punctuated equilibrium?Punctuated equilibrium is defined as the theory that proposes that once a species appears in the fossil record, the population will be stable, showing little evolutionary change for most of its geological history, with little or no morphological change. The condition is called statis.
This balance is the idea that evolution is rapid rather than following the slow, but steady path Darwin suggested. Long periods of stagnation with little activity are interrupted by intermittent bursts of activity in the case of extinction or emergence of new species.
Thus, Whale species gradually changing from land-dwelling mammals that walk on four legs to marine mammals without legs would be an example of an organism evolving through punctuated equilibrium. So, the correct option is (D).

Summarize sexual reproduction in plants. I need help please!!
Answer:
Plant reproduction is the development of new offspring that can be achieved through sexual or asexual reproduction in plants. By the fusion of gametes, sexual reproduction creates embryos, resulting in offspring genetically distinct from the parent or parents. Asexual reproduction creates new individuals, genetically similar to the parent plants, without the fusion of gametes.

In recent scientific history, the classification of the protist kingdom has changed several times. They are now grouped to consider their development over time instead of simply by what they look like or how they move. Which statement best describes the reason for these classification changes?
A. Traditional scientists did not have enough information about protists to attempt to clasify them.
B. Originally, scientists drew inaccurate conclusions about the classification of protists based on flawed data.
C. Changes in classification of this kingdom are made each time modern scientists discover a new species of protists.
D. The classification of protists changes as scientists learn more about how these organisms are related to each other and to members of other kingdoms.
Answer:
D
Explanation:
The statement that best describes the reason for these classification changes is the classification of protists changes as scientists learn more about how these organisms are related to each other and to members of other kingdoms. The correct option is D.
What are the characters of the protist kingdom?All eukaryotes that are not fungi, animals, or plants are collectively referred to as protozoa. It is a tremendously diverse group of species as a result.
Beyond a rather straightforward organizational structure, the eukaryotes that make up this kingdom, Kingdom Protista, do not share many characteristics.
Therefore, the correct option is D. The classification of protists changes as scientists learn more about how these organisms are related to each other and to members of other kingdoms.

Ocean salinity varies from place to place due to differing conditions in the environment
-true
-false
Ocean salinity varies from place to place due to differing conditions in the environment is a true statement.
How ocean salinity varies?It is not evenly distributed, but it does change temporarily and spatially with the oceans and seas.
This variation is both horizontally and vertically distributed; horizontal distribution refers to salinity changes at the ocean's surface level and vertical distribution, to salinity changes as the ocean's depth.
Several variables influence ocean salinity. They are global warming, evaporation, rainfall, river water input, ocean currents, atmospheric pressure, and wind direction. Oceans and seas have a 35 average salinity.
Therefore, It is not evenly distributed, although it does change momentarily and spatially with the oceans and seas.

Answer:
Explanation:How many grams are in 5.4 moles of iron (III) sulfate, Fe2(SO4)3?⇔⇔∉↑·ПНПёПсжЫЫЫЁ
Explanation:
Seaweed being eaten by a turtle is an example of an organism providing energy to a primary consumer. Therefore, the correct option is A.
What is a seaweed?The seaweed is a primary producer that captures energy from the sun through photosynthesis and converts it into chemical energy stored in organic compounds. The turtle is a primary consumer that obtains energy by consuming the seaweed.
Option B is incorrect because both the shrimp and the codfish are consumers. Option C is incorrect because this is an example of decomposition, which is the breakdown of organic matter into simpler compounds by decomposers such as bacteria.
Option D is incorrect because the oak tree is a primary producer that captures energy from the sun through photosynthesis. Therefore, the correct option is A.
