Answer:
It protects the seed until it matures
Explanation:
Pine cones don't have chroloplasts so they can't produce photosynthesis. Pine cones are rough and spiky and birds wouldn't want to put something rough and spiky in their nests where they raise their young. But it is rough and spiky enough to protect the seed until it's been dispered far enough to break open the shell and start growing.
Answer:
A.
It protects the seed until it matures.

Could someone help : how does the number of offspring that are produced by an individual typically compare with the fecundity of that individual? What factors create this (think of reproductive potential)
Answer:
The number of offspring produced is often related to the amount of parental care. Typically, the higher fecundity, the lower the amount of time parents devote to caring for the offspring.
The number of offspring that are produced by an individual typically varies with the fecundity, as the higher the fecundity, the lower the parental care per offspring, while a lower fecundity leads to more parental care.
What is parental care in the animal kingdom?Parental care refers to the behaviors of parents for the care of their offspring, and in the animal kingdom, parental care can take many forms, ranging from simple behaviors like providing food and shelter to more complex behaviors like teaching and training offspring and parental care is important for the survival and development of offspring, as it can improve an offspring's chances of survival by providing them with resources, protection, and guidance.
Hence, the number of offspring that are produced by an individual typically varies with the fecundity, as the higher the fecundity, the lower the parental care per offspring, while a lower fecundity leads to more parental care.

7. Which of the following processes DOES NOT produce new genetic combinations?
crossing over during meiosis
b. fertilization in sexually-reproducing organisms
c. independent assortment in gamete production
d. replication of DNA in mitosis
Replication of DNA in mitosis does not produce new genetic combinations. The correct option is d.
In mitosis, DNA replication does not result in novel genetic combinations. Somatic cells go through a process called mitosis, which produces two identical daughter cells with the same genetic makeup as the parent cell.
The DNA is properly duplicated during mitosis while keeping the same genetic sequence. Therefore, during this procedure, no new genetic combinations or variants are introduced.
The other processes, including crossing over during meiosis, fertilisation in sexually reproducing organisms, and independent assortment in gamete formation, all help to produce novel genetic combinations by recombining genetic material.
Thus, the correct option is d.

¿Qué efecto tiene para las cadenas tróficas la tala y deforestación de los organismos productores?
Answer:
tiene un efecto devastador sobre las cadena tróficas de ecosistemas terrestres
Explanation:
En una cadena trófica, los organismos productores, también conocidos como autótrofos, son aquellos capaces de convertir la energía proveniente del Sol (organismos fotosintéticos) o de la oxidaxión de compuestos inorgánicos (organismos quimiosintéticos) en nutrientes a través de la formación de enlaces de carbono que componen moléculas orgánicas tales como, por ejemplo, carbohidratos (es decir, celulosa, azúcar, etc). Por ejemplo, los árboles son organismos productores que usan la fotosíntesis para convertir la energía lumínica solar en energía química la cual es utlilizada por consumidores primarios (hervívoros) de la cadena trófica. Los árboles son organismos productores los cuales juegan un papel clave en ecosistemas terrestres, representando la principal fuente de alimento y nutrientes para diferentes consumidores primarios. Además, estos organismos autótrofos son también fundamentales porque generan oxígeno (O2) y capturan el dióxido de carbono (CO2) de la atmósfera, lo cual es un proceso clave para el sostenimiento de la vida en la tierra.

Identify the correct amino acid sequence for the mRNA strand ACG using the codon chart below.
Threonie
Serine
Lysine
Arginine
Answer:
option 4 is your answer
Explanation:
The correct amino acid for the ACG sequence is Threonine (Thr).
During translation, a messenger RNA (mRNA) sequence is read in the ribosomes to synthesize a polypeptide chain (i.e., a protein).
The correct order of triplets of nucleotides or 'codons' in the mRNA determines the order of amino acids in the nascent polypeptide chain.
Each codon determines a specific amino acid. In this case, the codon ACG encodes for the amino acid Threonine.
In conclusion, the correct amino acid for the ACG sequence is Threonine (Thr).

Rohit read an interesting fact that if diffusion were to move oxygen in our body, it is estimated that it would take 3 years for a molecule of oxygen to reach our toes from our lungs. Then what is the reason that it travels so fast?
Answer:
See the answer below
Explanation:
Oxygen moves fast around the human body due to the fact that there is a transportation system for it. The blood serves as the transporting medium for oxygen. Haemoglobin in the red blood cells picks up the oxygen and delivers them to places where they are needed in the body.

If an organism had 20 chromosomes, how many chromosomes would the daughter cell have after mitosis? After meiosis?
Answer:
After mitosis, the daughter cell has 20 chromosomes and after meiosis, the daughter cell has 10 chromosomes.
So the answer is 20 and 10
Answer:
[tex]\boxed {\boxed {\sf Mitosis: 20 \ chromosomes}}[/tex]
[tex]\boxed {\boxed {\sf Meiosis: 10 \ chromosomes}}[/tex]
Explanation:
Mitosis and meiosis are both types of cell divisions, but they are different.
Mitosis
1 cell division that results in 2 daughter cells used for growth, repair, and developmentThe cells are genetically identical with the same number of chromosomes as the parent cell.Meiosis
2 cell divisions resulting in 4 daughter cells for sexual reproduction The cells are genetically different and have half the number of chromosomes as the parent.The organism has 20 chromosomes.
Mitosis: same number of chromosomes=20 Meiosis: half the chromosomes= 20/2= 10After mitosis, the daughter cell has 20 chromosomes. After meiosis, the cell has 10.
After cytokinesis, how many cells have been formed from the parent cell?
Answer:
The cell now undergoes a process called cytokinesis that divides the cytoplasm of the original cell into two daughter cells. Each daughter cell is haploid and has only one set of chromosomes, or half the total number of chromosomes of the original cell.
Explanation:
The phragmoplast, a structure made up of membranes, actin filaments, and microtubules, controls the deposition of the new wall.
What is the role of cytokinesis in plant cell?Higher plant cells have a unique process for cytokinesis, in which the division of a new cell wall partitions the cytoplasm.
Inside the cell is the cell plate. The location of a preprophase band of microtubules and actin filaments determines where the cell plate is located.
After mitosis, a new cell wall must be created and inserted in plant cells during a process known as cytokinesis.
The cytoplasm of the parent cell is now divided into two daughter cells by a process known as cytokinesis in the cell.
Therefore, each daughter cell is haploid and has just one set of chromosomes, or half as many as the original cell.

Cancer is a disease related to the cell life span and cell division. If cancer cells were added to the data table, predict what would be written under the columns headed “Life Span” and “Cell Division.” Explain the reasoning underlying your predictions.
Many people live much longer than 5 years after their cancer diagnosis. The term does not mean a person will only survive for 5 years.
For example, 90% of people with breast cancer will be alive 5 years after the diagnosis of cancer.
Cell Division:Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues.

What unique characteristic does the bonding of carbon to other atoms have and why is this important for organic molecules?
Explanation:
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules. Individual carbon atoms have an incomplete outermost electron shell.The ability of forming long durable chain is an unique characteristic of Carbon that is important for organic molecules.
The Carbon can form four bond with different atom anf form a long chain of different size. These can also be branched. The long chains are very durable.
Silicon and some other elements can do so but the chains are relatively short and non-durable.
Therefore, the ability of forming long durable chain is an unique characteristic of Carbon that is important for organic molecules.
