Answer:

Positively charged.

Explanation:

An atom that has lost an electron is positively charged. When an atom loses an electron, it becomes positively charged because the number of protons in the nucleus now exceeds the number of electrons, resulting in a net positive charge. The other answer choices do not apply to an atom that has lost an electron.

In the researcher's sample, 80% of randomly selected ears of corn were yellow and had smooth skin.

50 ears of corn, randomly selected from a field, were studied by the researcher. There are 50 ears in total, of which 40 are golden and smooth skinned. Determine the ratio of ears with pale skin and smooth skin.

Percentage = (Number of ears with the specified characteristics / Total number of ears) * 100

When we put the values in the formula, we get:

Percentage = (40 / 50) * 100

Simplifying the expression:

Percentage = 0.8 * 100

So, the final percentage will be:

Percentage = 80%

Therefore, 80% of the randomly selected ears of corn in the researcher's sample were yellow in color and had a smooth skin texture.

Answer:

c) repeat the cell cycle continuously

Explanation:

Cell division is a normal phenomenon for all cells as this is the way the cell reproduces and gets repaired in living organisms. However, some cells, due to mutation, keeps dividing and proliferating to form tumours. These cells are called CANCER cells. A normal cell undergoes cellular repair at certain checkpoints of the cell cycle. The checkpoints are necessary to determine a faulty cell and stop its division.

However, cancerous cells do not undergo any repair, which is why they do not enter the G0 phase as mentioned in the question. They keep on dividing out of control without death by repeating the cell cycle continuously.

The organs of the urinary system include the kidneys, ureters, bladder, and urethra.

The kidneys are the primary organs of the urinary system and are responsible for filtering waste products and excess fluids from the blood to produce urine. They regulate the body's water and electrolyte balance, maintain blood pressure, and help in the production of certain hormones.

The ureters are long, muscular tubes that transport urine from the kidneys to the bladder. They propel urine through peristaltic contractions, ensuring the unidirectional flow of urine.

The bladder is a hollow, muscular organ that stores urine until it is eliminated from the body. Its muscular walls expand to accommodate urine and contract during urination to expel urine through the urethra.

The urethra is a tube that carries urine from the bladder to the external opening of the body. In males, it also serves as the passageway for semen during ejaculation.

Together, these organs work in a coordinated manner to remove waste products, maintain fluid balance, and eliminate urine from the body. They play a crucial role in the excretory function of the body and help maintain overall homeostasis.

Answer:

Earthworms create a moist local environment for gamete fusion by secreting mucous. When two earthworms first mate, they create a slime tubule around themselves and exchange sperm. Earthworms are hermaphroditic, so each worm fertilizes the other.

In nature, not all individuals in a biological population has the same reproductive success. Additionally, the reproductive succes of an individual may be related to a heritable trait. Disruptive (natural) selection is operating when indivuals with extreme values for an heritable trait have a greater reproductive succes that the ones with intermediate values for the same trait.

An energy pyramid is a diagrammatic representation of the relationship between the producers, consumers, and decomposers within an ecosystem. It shows the flow of energy through the different trophic levels in an ecosystem. An energy pyramid shows that there is less energy available to organisms at higher trophic levels than at lower trophic levels. 10% of 6,250 kcal is equal to 625 kcal.

If the kelp receive 625,000 kcal of energy from the sun, the available energy to the otter on the 3rd trophic level will be 625 kcal.  The transfer of energy from one trophic level to another is only around 10%. So, if the kelp receives 625,000 kcal of energy from the sun, the primary consumer or the 2nd trophic level will only get around 62,500 kcal of that energy (since 10% of 625,000 is 62,500). Then, the secondary consumer or the 3rd trophic level will only receive 10% of the energy that was available to the primary consumer. Therefore, 10% of 62,500 kcal is equal to 6,250 kcal. Finally, the otter on the 3rd trophic level will only get around 10% of the energy that was available to the secondary consumer. Therefore, 10% of 6,250 kcal is equal to 625 kcal.

Mendelian inheritance states that traits are determined when offspring receive one allele for each trait from each parent.

Mendelian inheritance, named after the Austrian monk Gregor Mendel, explains how traits are passed on from parents to offspring. The basic principle of Mendelian inheritance is that traits are determined by the inheritance of alleles, which are different forms of a gene.

1. Alleles: Genes exist in pairs, with one allele inherited from each parent. These alleles can be either dominant or recessive. Dominant alleles exert their effects even if only one copy is present, while recessive alleles require two copies to be expressed.

2. Gamete Formation: When an organism produces gametes (sperm or eggs), it undergoes a process called meiosis. During meiosis, the pairs of alleles separate, so that each gamete receives only one allele for each trait.

3. Fertilization: When two gametes (one from each parent) combine during fertilization, the resulting offspring inherits one allele for each trait from each parent. This is why offspring typically exhibit a combination of traits from both parents.

4. Punnett Square: To predict the possible combinations of alleles in offspring, a Punnett square can be used. This is a grid that helps determine the probability of different genotypes and phenotypes.

5. Dominant and Recessive Traits: If a dominant allele is present, it will be expressed in the offspring's phenotype. However, if both alleles are recessive, the recessive trait will be expressed.

Overall, Mendelian inheritance provides a framework for understanding how traits are inherited and passed down from one generation to the next through the transmission of alleles from each parent.

The given statement the first class lever is the most common lever in the human body is False.

The most common lever in the human body is actually the third class lever. A lever is a simple machine consisting of a rigid beam (or bar) that pivots on a fulcrum to transmit or increase force. In a third-class lever, the effort force is applied between the fulcrum and the resistance force. This lever arrangement is seen in many parts of the human body, such as the muscles and joints.

An example of a third-class lever in the human body is the biceps brachii muscle in the arm. The elbow joint acts as the fulcrum, the biceps muscle applies the effort force, and the weight of the forearm or any resistance is the resistance force. Other examples of third-class levers in the body include the quadriceps muscle in the thigh and the muscles in the fingers.

While first-class levers are also present in the human body, they are not as common as third-class levers. In a first-class lever, the fulcrum is located between the effort force and the resistance force. An example of a first-class lever in the body is the head resting on the atlas vertebra, where the neck muscles provide the effort force, the joint acts as the fulcrum, and the weight of the head is the resistance force.
