One of the features that can make an animal to have a long lifespan is the size, due to the protection conferred by its size. Also, some animals like the elephant and the whale, have a slow cell replication rate, what reduces the risk of cancer, because the less they replicate, the fewer mutations can be caused.
Moreover, many animals have developted many ways of protecting themselves from mutations, such as having several copies of an important gene.
A list of some animals with long lifespan:
- Bowhead whale: potentially 200+ years old.
- Rougheye rockfish: 200+ years old.
- Freshwater pearl mussel: 250+ years old.
- Greenland shark: 272+ years old.
- Tubeworm: 300+ years old.
- Glass sponge: 10,000+ years old.
- Hydra: also potentially immortal.
A parent cell from a human starts with 23 pairs of chromosomes; how many pairs of chromosomes will be in each new cell following cytokinesis?
Answer:
46 I belive! hope this helps
23 pairs of chromosomes, or 46 chromosomes will be present in the new cells formed after cytokinesis.
The DNA is duplicated during interphase. Consequently, one chromosome is present in two copies.
This indicates that the parent cell now contains 46 pairs of chromosomes.
However, the cell divides into two during cytokinesis, leaving each daughter cell with 46 chromosomes or 23 pairs of chromosomes.
What is Cytokinesis?A single eukaryotic split into two daughter cells during the cell division process known as cytokinesis. After the latter phases of mitosis and meiosis' nuclear division, the process of cytoplasmic division starts. As the daughter cells separate during cytokinesis, the spindle apparatus divides and carries duplicated chromatids into the cytoplasm. Thus, it guarantees that the chromosomal number and complement are preserved from one generation to the next and that, barring exceptional circumstances, the daughter cells will be functional duplicates of the parent cell. Each daughter cell starts the cell cycle's interphase after telophase and cytokinesis are finished.To learn more about Cytokinesis, refer to:

MENTION 5 IMPORTANCE OF FUNGI IN AGRICULTURE
Fungi are in charge of decomposing organic matter and releasing carbon, oxygen, nitrogen, and phosphorus into the soil and the atmosphere along with bacteria. Many domestic and industrial operations, including the production of bread, wine, beer, and some cheeses, depend on fungi.
Fungi are used by people for a variety of things, including as food and in food preparation. Fungi are also used by people to manage pests. Fungi can also be utilized to create human hormones, citric acid, and medicines. Additionally, fungi are model study organisms.
Most ecosystems depend on fungi as significant decomposers.
Most fungi's main function is to maintain the natural world. Fungi and bacteria both play a crucial role in the soil food web as decomposers. They transform difficult-to-digest organic material into forms that other species can utilise.In addition to producing proteins, carotenoids, and other elements for food, fungus also serve as a source of food.

acid sequence?
A Okazaki Fragments
B Exons
C Cap and Tail
D Introns
Correct answer is option B.
Exons are what remain in mature mRNA and ultimately code for amino acids.
What is Exon strand in mRNA?Exons are protein-coding sections of an RNA transcript or the DNA that encodes it. Exons can be separated by introns, which are sections of DNA that do not code for proteins.Exons are gene segments that code for proteins. To create a final product, they are transcribed and translated.Exons are nucleic acid coding sequences that are found in mRNA. Introns are non-coding sequences found in DNA that are removed by RNA splicing prior to translation. Intron sequences change rapidly over time, whereas exon sequences are highly conserved.Each gene has an average of 8.8 exons and 7.8 introns.

A football player kicks a ball with a mass of 0.42 kg. The average acceleration of the football was 14.8 m/s².
How much force did the kicker supply to the football?
The kicker supply to the football is 6.22 N.
Solution:
F = m*a - A
F = Force = ?
m = mass = 0.42 kg
a = acceleration = 14.8 m/[tex]s^{2}[/tex]
Plug the values in equation A:
F = 0.42 * 14.8
F = 6.216 N
F = 6.22N.
An NFL kicker's foot average force during a kick is about 450 pounds 2002 N and the ball can even deform on contact so kicking is a large power imbalance. A soccer ball is kicked with the power of the leg muscles. Therefore, the forces exerted are muscle forces. Strength is the force produced by using a body part such as an arm or leg. Since there is contact between surfaces, it is the contact force created by muscle activity. This phenomenon is commonly seen in soccer games when a player tries to catch a ball that has been thrown into the air.

Science is the use of evidence to construct testable explanations and predictions of natural phenomena, as well as the knowledge generated through this process. Lizards with the longest legs are able to climb in order to reach high sources of food and escape the ground when floods or storms occur. Weather conditions for seven years are shown below.How might natural selection act on the lizard population if this pattern continues over time?
Solution:
Note that according to the table, the rainfall increased each year, which will endanger organisms that are above ground and cannot climb. Now, because the longer-legged lizards can climb to reach high food sources and escape from the ground when floods or storms occur, then these members of the population have better characteristics, depending on the environment they are adapted to (lots of rain ). Therefore, according to natural selection, these lizards will probably have a higher survival rate and therefore will be more likely to prevail and their genes to be inherited from generation to generation.

Testosterone is a sex hormone that has numerous physiological functions. It is thought to control sex drive (libido), bone density, fat distribution, muscle mass and strength, and red blood cell and sperm production in men.
The testicular Leydig cell synthesizes testosterone (T) from cholesterol under the control of the pituitary gonadotropin LH. The gonads produce testosterone, though the adrenal glands in both sexes produce a small amount.

Why are sago palms gymnosperm?
How do they achieve fertilization/pollination?
Are they gametophyte dominant, sporophyte dominant, 50/50, or sporophyte only?
Sago palms or Cycas revoluta is gymnosperms because they reproduces through an exposed ovule or seed.
In gymnosperm Pollen from male cones blows up into upper branches, where it fertilizes female cones. Cycas revoluta is a cycad, not an actual palm. Pollination in gymnosperms involves pollen transfer from the male cone to the female cone. during transfer, the pollen develops to form the pollen tube and the sperm for fertilizing the egg.
In gymnosperm ovaries are absent, double fertilization does not take place, As male and female gametophytes are present on cones rather than flowers, and wind is the main source pollination.
