How does this model support the conclusion that cells need to have a high amount of surface area relative to their total volume?
Answer:
Due to increase of surface area, the nutrients move efficiently inside the cell.
Explanation:
The cells need to have a high amount of surface area as compared to their total volume because with increase of surface area, the nutrients move efficiently inside the cell. A large surface area to volume ratio indicates that the cell can be efficient in moving nutrients and waste materials around using through the process of diffusion but when the volume increases instead of surface area, the efficiency of the cell decreases, and cells won't be able to do its job efficiently.

Explica el impacto del desarrollo de las técnicas moleculares en los sistemas de clasificación de los organismos.
Answer:
Las técnicas moleculares, especialmente aquellas basadas en la manipulación del material genético, permitieron automatizar el proceso de identificación y clasificación de especies
Explanation:
Las técnicas moleculares usadas para la clasificación de organismos son aquellas principalmente relacionadas a la manipulación de su material genético. En especial, las técnicas de extracción de ADN, amplificación mediante la reacción en cadena de la polimerasa (PCR) y posterior secuenciación han posibilitado automatizar el proceso de clasificación de organismos. Los marcadores moleculares de ADN basados en secuencias génicas evolutivamente conservadas tales como, por ejemplo, la secuencia del gen Citocromo Oxidasa I (COI) en animales, son ampliamente usados para automatizar este proceso de identificación y clasificación de nuevas especies.

Brown eyes are d o m i n a n t over blue eyes in humans. A brown-eyed male marries a blue-eyed female. They have 10 children, all brown-eyed. Can we be certain that the man is h o m o z y g o u s d o m i n a n t? If the 11th child has brown eyes, will that prove the father's genotype is? Explain your reasoning, or show a Punnett Square. (word is spaced out because of brainly's guidelines.)
Answer:
No.
Explanation:
Based on the punnets square (assuming that eye color is a one gene trait in this question) There is a 75% chance they would have a child with brown eyes and a 25% chance that the child would have blue if the father is heterozygous. Theoretically the father could be heterozygous and still have 11 brown eyed kids. This just means that the Dad always passed down his dominant gene.

Give the genotype for male and female sex chromosomes (XX,
XY).
FEMALE:
MALE:
Answer:
Human X and Y chromosomes determine the biological sex of a person, with XX specifying female and XY specifying male. Although the Y chromosome contains a small region of similarity to the X chromosome so that they can pair during meiosis, the Y chromosome is much shorter and contains many fewer genes.

Draw a food chain that includes the ants, fungal gardens, mold, and bacteria. Label the drawings and add arrows to show how the four organisms interact.
Answer:
Symbiosis and decomposers.
Explanation:
The ants feed on both plants and insects so we can say that ants are omnivorous. They make a symbiotic relationship of mutualism with fungi such as mold which helps the ants to breakdown the cellulose of plants whereas plants provide habitat to fungi. The bacteria feeds on the dead body of ants and release nutrients by performing the function of decomposition so bacteria acts as decomposer so in that way these four organisms interact with each other.

Vaping can expose you to nicotine, and that can cause cravings and other symptoms of addiction. It can also expose your lungs to toxic metals like nickels, lead, chromium, tin, and aluminum. Nicotine changes the way your brain works so as a teen your brain is still developing and that can make it where you're more vulnerable to nicotine addiction. You inhale 3 chemicals when you vape. When addicted to vaping you can get popcorn lung and the effects are, coughing, wheezing, chest pain, shortness of breath. It also can affect your memory. 1. Diacetyl: This food additive, used to make the flavor, will damage small passageways in the lungs. It's also a compound found in foods and additives used for dairy flavoring. It's found in brown flavors, such as caramel, butterscotch, and other sweeteners. 2. Formaldehyde: This can cause lung disease and contribute to heart disease. It's a colorless, strong-smelling gas used in making building materials and many household products. It is also used in pressed-wood products, like particle board, plywood, and fiber board. 3. Acrolein: It's most often used as a weed killer, this can also damage lungs. It's a colorless liquid with a piercing, acrid smell. The smell of burnt fat. Vaping has some effects like tobacco as in picking at your face so much it leaves scars. It also gives you mood swings. Vaping can lead to other addictions in life. You will feel more anxious than usual. It can also lead to cancer, diabetes, eye problems, sickness, gum infection and disease, heart problems, impotence, infertility, lung disease, pregnancy complications. If you're athletic it would be harder to do your sport because you would lose breath faster and you wouldn't be able to do it for a long time. So if you play sports and you vape you will have to quit your sport or quit vaping. It also makes you depressed (more) because of the brain damage you're causing .
.The millionaire, Mr. Big, has just died. He has left behind a wife, daughter and a large inheritance. The news of his death has brought forth 2 men who claim to be the long lost son of Mr. & Mrs. Big. Before Mr. & Mrs. Big were married, they had an illegitimate child and had placed him up for adoption. They had tried to find him after they became wealthy but had no luck in locating him. A DNA sample was taken from Mrs. Big, the Big daughter and the two men who claim to be the long lost son. Which, if any, of the men are telling the truth? Analyze the DNA sample below to answer the question. Explain how you determine the correct answer.
Answer:
Explanation:
use this it might help
As per the question, DNA analysis can be used to determine the biological relationship between individuals, so if the DNA of the two men claiming to be Mr. Big's son matches that of Mrs. Big and Mr. Big's daughter, it would be strong evidence that they are indeed Mr. Big's biological children.
What is DNA analysis?
DNA analysis is a scientific technique that is commonly used to identify biological relationships between individuals. It works by comparing the genetic markers or sequences of the DNA samples collected from the individuals in question. DNA is the genetic material that contains the genetic instructions for the development and function of all living organisms. In the case of the Big family, if one or both of the men claiming to be Mr. Big's son have a DNA sequence that matches the genetic markers of Mrs. Big and the Big daughter, it would be a strong indication that he is indeed the biological son of Mr. Big. The DNA analysis would be able to provide information about the probability of the biological relationship based on the number of matching genetic markers or sequences.
Hence, DNA analysis can be used to determine the biological relationship between individuals, so if the DNA of the two men claiming to be Mr. Big's son matches that of Mrs. Big and Mr. Big's daughter, it would be strong evidence that they are indeed Mr. Big's biological children.
