What statement best describes symbiotic relationships?
O Different species live in close associations in an ecosystem.
Abiotic factors interact in an ecosystem.
O Saprophytes respond to abiotic changes in an ecosystem.
O Ecosystem feeding levels show changes in energy.
The statement that best describes symbiotic relationships is different species live in close associations in an ecosystem. The correct option is A.
What is the symbiotic relationship?Symbiotic relationships are those relationships in which two organisms live together and depend on each other for nutrition and space. In symbiosis, both organisms help each other.
For example, cattle and egret. The egret is a wading bird that feeds on the ticks or lice of the cattle. Eating them through the body helps clean the body of the cattle, and it also provides nutrition to the egret.
In an ecosystem, different organism lives together. Tress provides space and food for the animals. Animals help in the dispersion of seeds of various plants. In short, it is symbiosis.
Thus, the correct option is A. Different species live in close associations in an ecosystem.

Answer:
Gametes from both dogs are needed to maintain the correct number of chromosome in the offspring
Explanation:
Reproduction in dogs is a sexual process. During the process, haploid gametes from both the male and the female (sperm from males and eggs from females) fuse together in a process known as fertilization in order to produce diploid offspring.
The haploid gametes ensure that the offspring produced during fertilization has the correct (diploid) number of offspring. Because the production of gametes involves meiosis and crossing over of genetic materials between chromosomes, offspring produced by sexual reproduction are usually genetically different from one another. The random fusion of gametes further ensures that offspring from the same parents are different from one another.

Question 5 (1 point) Which letter represents the trough of the wave? B
A
C
E
D
WILL GIVE BRAINLY
Answer:
D
because trough is the lowest or the minimum point and here D represents it.
:))
The point (D) represents the trough of the wave.
What do you mean by wave?In physics, mathematics, and related fields, a wave is a propagating dynamic disturbance of one or more quantities. Waves can be periodic, in which case those quantities oscillate repeatedly about an equilibrium value at some frequency.
Moreover, a wave is a disturbance that moves energy from one place to another. Only energy — not matter — is transferred as a wave moves. The substance that a wave moves through is called the medium.
Hence, the highest surface part of a wave is called the crest, and the lowest part is the trough. The vertical distance between the crest and the trough is the wave height. The horizontal distance between two adjacent crests or troughs is known as the wavelength.

HELP ASAP
Answer:
Metabolism is the chemical reactions that take place inside a living organism. The reaction occurs in the cells. Digestion can be the best association to metabolism. The metabolic system recognizes which substances can be nutritious or poisonous. In order to complete this process, water is needed. The chemicals are dissolved in water and transported. Without water, no reaction can take place.
Metabolism is considered as the set of life-sustaining chemical reactions within the living organism’s body cells.

Introduction:
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves. Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell.
Materials:
• Microscope
• Prepared slide of muscle tissue
• Prepared slide of some internal organ such as the kidney, liver, or heart
• Prepared slide of erythrocytes, or leukocytes (from blood)
Instructions:
1. Place one of the prepared slides of animal tissue on the stage of the microscope.
2. Focus the microscope on low power. Then change to the high-power objective. Focus on the tissue, and note the cells.
3. On a separate sheet of paper, draw an individual cell that you see in the tissue. Note the shape of the cell and its other distinctive characteristics.
-What do you think the function of this cell might be?
4. Repeat Steps 1 and 2 using the other prepared slides.
5. On a separate sheet of paper, draw individual cells from the other prepared slides examined.
Questions:
What do you think the functions of the other cells drawn might be?
- (i think this differs on person to person so may need to do it yourself)
If all of the different kinds of cells which you observed had been taken from the same organism or individual, would they have all had the same genetic information?
- Yes, the cells will have the same genetic information. However, the particular combination of genes that are turned on (expressed) or turned off (repressed) dictates cellular morphology (shape) and function. Essentially meaning that though the cells share the same genetic information they do not necessarily share the same functions.
Consider specialization: What biological concept or occurrence is demonstrated by the different kinds of cells which were observed?
- Though these cells have the same DNA, they all have different phenotypes. The phenotypes are different because the cells appear different under the microscope. The cells do this by expressing different genes at different rates. For example, the blood cell is expressing the gene to make hemoglobulin while the other cells are probably expressing different genes that allow them to be specialized. Cells differentiate which means that they are becoming more specialized. Epigenetics focuses on how cells become more specialized.
Why is it important?
- This is important because it allows different parts of the body to carry out their crucial functions necessary for the whole body to run properly.

Identify the correct transcriptions between DNA to mRNA
CTGACTGACC to GACUGACUGG
OGGATCTCTCA to CCTAGAGAGT
TACTACGGAT to UTGUTGCCTU
AGCTCCGATC to UCGAGGCUAG
OGCTAATCGAT to CGAUUAGCUA
CATCTATGAG to GTUGUTUCTC
No
Answer:
CTGACTGACC to GACUGACUGG
AGCTCCGATC to UCGAGGCUAG
GCTAATCGAT to CGAUUAGCUA
Explanation:
Transcription is the process whereby a DNA template is used to form a mRNA molecule in the nucleus following the complementary base pairing rule. The complementary base pairing rule as postulated by Chargaff states that an Adenine base will always pair with Thymine (Uracil in RNA) while Guanine base will always pair with Cytosine i.e A-U, G-C.
N.B: Thymine in the DNA will yield Adenine in the mRNA while Adenine in the DNA will yield Uracil in the mRNA.
Hence, according to this question, the following DNA templates will be transcribed as follows:
1. CTGACTGACC to GACUGACUGG
2. AGCTCCGATC to UCGAGGCUAG
3. GCTAATCGAT to CGAUUAGCUA

Why is the line graph a curve instead of a straight line?
Answer:If it's important to display the exact values, then the straight lines do a much better job. But often you'll find that what matters is the trend and the precise measurements are secondary. ... A straight line suggests that the value between the two measurements increased linearly, while a curved line suggests otherwise.
