What body structured indicate that mammals descended from reptiles?
Explanation:
Many of the most important and diagnostic mammalian characteristics serve to further intelligence and sensibility, promote endothermy, or to increase the efficiency of reproduction or the securing and processing of food.
Basic structural body plan is inherited from Therapsid mammal-like reptiles.
Survival through mammalian evolution was perhaps due to their ability to move and to think more quickly than their Archosaurian counterparts.
Morphological trends were toward structural simplification:
� skull and jaw bones lost or reduced in size
� limbs and limb girdles simplified, reduced, and less laterally splayed
Fossil record provides little evidence on when endothermy actually developed.
Diagnostic or Distinguishable Characteristics of Mammals:
Soft Tissues
Skin glands: Mammalian skin contains several kinds of glands not found in other vertebrates.
Mammary Glands: Provide nourishment for the young during their postnatal period of rapid growth.

If the growth rate is constant, how many jellyfish lived at the end of the pier 10 days ago?
Answer:
0
Explanation:
Since the constant is +10 every day (+15-5) 10 days ago the population would have been zero (100 - 10(15-5))
Which of the following is NOT a resource that organisms fight over for survival?
Reproduction
Food
Water
Oxygen
Shelter
Answer:
Oxygen
Explanation:
Oxygen because when was the last time you saw one organism beating up another organism because that one was taking too much, its air, or air near it. Organism, however, do fight for mating rights (Reproduction), Food, Water, and Shelter because these are things that could go scarce, unlike oxygen which is always being pumped out by plants.

What disease can result from uncontrolled cellular division?
Cancer is a disease that can result from uncontrollable cellular division.
Molecules in a certain medication attach to receptors
on nerve cells. This prevents the normal
chemical signal from binding to the receptor. One
immediate result of taking this medication might be a
disruption in the ability of
A) the body to produce reproductive cells
B) cells to communicate with each other
C) cells to synthesize proteins
D) the body to convert inorganic material into
organic nutrients
Answer:
It would be B.
Explanation:
This is because it immediatly prevents the cells from communicating with each other.
One immediate result of taking this medication might be a disruption in the ability of the cells to communicate with each other in the brain. Thus, the correct option is B.
What are Mechanoreceptors?Specialized sensory receptor cells that are present in the brain are called mechanoreceptors. These are often encapsulate afferent fibers to help tune the afferent fibers to different types of somatic stimulation in the brain.
Neurotransmitters are the chemical messengers without which the body cannot function. The main function of neurotransmitters is to carry chemical signals from one neuron to the target cell. The target cell can be another nerve cell, a muscle cell or a gland.
The molecules which attach to the receptors on nerve cells and prevent normal chemical signaling of the cell shows an immediate disruption in the ability of the cells to communicate with each other.
Therefore, the correct option is B.

can someone pls help me
Answer:
Explanation:
a. Since both the parents are carriers, they have one allele that is the gene for the normal trait and one gene that is for the sickle cell trait. So the genotypes of the parents are Hh
b. If we use a punnett square:
H h
H HH Hh
h Hh hh
Genotypic ratio: 1 HH: 2Hh: 1hh
Phenotypic ratio: 1 normal blood cell: 2 sickle cell carriers: 1 sickle cell disease
In a cross between two heterozygous tall and purple flowers (TtPp x TtPp), what would the
ratio be?
Answer:
9:3:3:1
Explanation:
This question involves two different genes coding for height and flower color respectively. The first gene posseses allele T (dominant) and t (recessive) while the second gene possesses allele P (dominant) and p (recessive).
According to this question, two heterozygous tall and purple flowers are crossed i.e. (TtPp x TtPp). Each parent will produce the following gametes combination:
TtPp - TP, Tp, tP, tp
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
T_P_ (tall, purple) = 9
T_pp (tall, white) = 3
ttP_ (short, purple) = 3
ttpp (short, white) = 1
Hence, the ratio of this cross is 9:3:3:1

B. They are both forms of cell division.
C. They produce the same number of daughter cells.
D. They are both caused by mutations.
5.How are mutations and meiosis similar? (1 point)
A. They both can pass on genetic variations that can be inherited.
B. They both impact the phenotypes of somatic cells.
C. They both always sort genetic information in the gametes.
D. They both can only originate through the process of reproduction.
Meiosis and mitosis are both types of cell division. Somatic mutations can be generated by mitosis, whereas germline (meiotic) mutations can be generated by meiosis.
Meiosis is a type of cell division that is specific to cell sex cells (Option C).The outcome of meiosis is four haploid (n) daughter cells, which develop into gamete/sex cells. Genotyping helps scientists to compare similarities found in reference sequences to determine any potential relations (Option C).Genotyping is a technique used for identifying individuals by sequencing and then comparing genetic sequences.Somatic cells are different from gametes because somatic mutations are not passed to the next generation (Option C).Somatic mutations cannot be inherited, whereas germline mutations in the gametes can eventually be passed onto offspring.Mitosis and meiosis are similar because they are both forms of cell division (Option B).Mitosis is a type of cell division that generates two identical daughter cells, each one containing the same genetic information as their parent cell. On the other hand, meiosis is a type of reductional cell division that generates four haploid (n) daughter cells from a diploid (2n) parent.Mutations and meiosis are similar because they both can pass on genetic variations that can be inherited (Option A).Meiosis creates genetic variation by the process of crossing over or recombination, which is the interchange of genetic material between non-sister chromatids.In conclusion, meiosis and mitosis are both types of cell division. Somatic mutations can be generated by mitosis, whereas germline (meiotic) mutations can be generated by meiosis.

Earth's northern hemisphere generally experiences warmer temperatures in July than it does in January. Which statement explains why?
A. Sunlight shines more directly on the northern hemisphere in July.
B. Sunlight in the northern hemisphere is more spread out in July.
C. The interior of the Earth heats the northern hemisphere more in July
D. The northern hemisphere is tilted away from the Sun in July
Answer:
D
Explanation:
The northern hemisphere is tilted away from the Sun in July causing Earth's northern hemisphere commonly founds warmer temperatures in July than it does in January, hence option
Why are seasonal changes occur on Earth?When Earth is tilted over its axis, this causes seasons to occur on Earth during various months, this movement around the Sun is the major cause of seasons on Earth.
In July month, the northern half of Earth tilts toward the sun, temperature of the land increases, which heat up easier than the oceans. While in January, it's difficult for the sun to heat the oceans, observing cooler average global temperatures, although the Earth is closer to the sun.
Therefore, July experiences warmer temperatures because the northern hemisphere is tilted away from the Sun in July.

Answer:
The core controls and controls the exercises of the cell (e.g., development and digestion system) and carries the qualities, structures that contain the innate data.
Atomic pores, little channels that span the atomic envelope, let substances enter and exit the core. Each pore is lined by a set of proteins, called the atomic pore complex, that control what atoms can go in or out.
The core is spheroid in shape and isolated from the cytoplasm by a layer called the atomic envelope. The atomic envelope confines and ensures a cell's DNA from different atoms that seem incidentally harm its structure or meddled with its handling.
