if an earthworm is 18mm long and is photographed and the picture is magnified 2.5x how long will it be in the picture?
Answers
Answer:
The earthworm will be 45 mm long in the picture
Explanation:
From the problem, we can take the original size of the earthworm to be 18mm.
Magnification can be obtained using the formula:
magnification = observed size/ original size.
Recall, we are given that the magnification is 2.5.
Hence, can evaluate the size in the picture to be
2.5 X 18mm = 45mm
I NEED HELP PLZ ITS DUE TODAY. The sun produces a great amount of energy with sound and lights. We enjoy the sun's light and heat waves on Earth, but cannot hear any sound of the sun. Explain this phenomenon in terms of mechanical waves and electromagnetic waves. (10 Points)
Answers
Answer:
See explanation
Explanation:
First of all, we have to know the difference between a mechanical wave and an electromagnetic wave.
A mechanical wave requires a material medium for propagation. It does not travel through space. An electromagnetic wave does not require a material medium for propagation and it can travel through space.
Light and heat are electromagnetic waves. They both belong to the electromagnetic spectrum. On the other hand, sound is a mechanical wave.
While heat and light can travel through space, sound can not because it is a mechanical wave. Sound has to pass through gas molecules and there is no gas in outer space.
Hence, we enjoy the sun's light and heat waves on Earth, but cannot hear any sound of the sun.

What is the structure inside of the nucleus called and the name of the phase of the
picture below?
a. chromatid and interphase
b. chromosome and prophase
C. chromatin and interphase
d. centromere and mitosis
Answers
you haven't added a picture
Explanation:
But if you can describe the picture I can answer it
The nucleus is the major and the central organ of the cell. The structure inside of the nucleus is chromatin and the phase is interphase.
What is chromatin and interphase?Chromatin is a complex structure present only in the eukaryotic cells that are composed of protein and DNA. It is required for the packaging of the long DNA threads into a compact and dense form.
Chromatin makes up the chromosome and is the packaging element of the genetic material. The basic and smallest unit of the chromatin is the nucleosome.
Interphase is one of the cell cycle periods that contain the non-dividing phase. The G1, S and the G2 phase of the cell cycle are part of the interphases.
In this phase, the cell undergoes the process of replication or duplication and cell growth. Not the actual division of the cell occurs instead it prepares the cell for the division.
Therefore, option c. interphase and chromatin are the phases and the structures present inside the nucleus.

Which of the following statements about metabolism are true? 1) Catabolism is the process in which complex substances are broken down, yielding a net output of energy. 2) Metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways. 3) Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides. 4) All organisms require an external source of energy, such as glucose or sunlight, for metabolic energy.
Answers
Answer:
the answer is 1), 2) and 3)
Explanation:
Metabolism can be defined as all the chemical reactions inside a cell that are required to carry out cellular functions (e.g., reproduction, growth, development). The metabolic reactions can be divided into anabolic and catabolic reactions. Anabolic reactions refer to metabolic reactions that require energy in order to construct new molecules from smaller ones (i..e., biosynthesis). Anabolism comprises endergonic metabolic pathways which are fueled by the use of energy (e.g., cellular ATP). On the other hand, catabolic reactions refer to metabolic reactions where larger molecules are separated to form smaller ones. Catabolic reactions are exergonic because they do not require energy (for example, reactions involved in cellular respiration).
Fruit color in a particular plant is controlled by a set of three quantitative traits that work in an equal and additive manner. Each trait has two alleles (i.e., A and a); each allele represented by a capital letter produces one dose of yellow pigment, while alleles represented with lower case letters do not produce any pigment at all. How many different shades of yellow fruit color are there
Answers
Answer:
7
Explanation:
The number of distinct shades of fruit color would be 7. It is given that the color is dominated by a group of three QTL(quantitative traits) with each trait having two alleles(A,a). Out of these two alleles, one represented by a capital letter(A) generates a single dose of yellow pigment while the latter represented by a smaller case letter(a) does not generate any pigment. Since there is no environmental effect, the number of various yellow shades would be 7 through the combinations of yellow and colorless pigments(A/a, A/a, A/a, A).

- Which occurrence is the result of the cell cycle in unicellular organisms?
A. cell repair
B. cell growth
C. cell replacement
D. cell reproduction
Answers
Answer:
D
Explanation:
Cell reproduction is the result of the cell cycle in unicellular organisms. The correct option is D.
What is cell reproduction?Cells split to produce multiple cells with similar, if not identical, contents. This process is known as cellular reproduction.
Nuclear division during mitosis produces two somatic cells that are genetically identical to the parent cell and have the same genetic complement.
Asexual reproduction in prokaryotes takes the form of cell division in unicellular organisms.
When an organism splits in half, it creates two totally distinct daughter cells, a process known as binary fission. The daughter cells are identical to the parent cells genetically.
Most of the time, Paramecium reproduces asexually via budding, however in poor circumstances, they produce sexually.
Unicellular organisms have a variety of asexual reproduction strategies, including multiple fission, fragmentation, and budding.
Thus, the correct option is D.
