Which is the most likely result if the Ubx gene was activated either before or after it normally is activated in the sequence of Hox gene expression?


A. The insect develops slightly shorter or longer abdominal legs.

B. The insect develops normal body parts at either a slower or more rapid rate.

C. The insect develops normal body parts but in an altered time sequence.

D. The insect develops legs in other parts of its body.

Answers

Answer 1

Answer:

D. The insect develops legs in other parts of its body.

Explanation:

HOX genes, also known as homeotic genes, are evolutionarily conserved genes (containing homeobox sequences) that encode master regulators of embryonic development in animals. Hox genes modulate the body plan of an embryo along the head-tail axis. In general, these genes are arranged in the same order as they are transcriptionally expressed along the anteroposterior body axis. Moreover, Ultrabithorax (Ubx) is a Hox gene that is responsible for the proper development of the third thoracic segment in insects. In Drosophila, it has been shown that different segments of the leg regulate their size in response to Ubx expression.

membrane
The movement of waste substances into, but not out of the cell is controlled by the
cell membrane
The cell membrane is inflexible and cannot control the movement of substances into

The cell membrane does not surround the cell so it plays no role in the movement of
substances

Answers

Answer:

The movement of specific substances into and out of the cell is controlled by the cell membrane.

Explanation:

The cell membrane is permeable, so it allows for the passage of substances both into and out of the cell. It is also selective, so only specific substances can enter and exit the cell.

Chromosome

Answers

Answer:

- DNA is wrapped around nucleosomes and condensed into chromosomes.

- Proteins affect the traits and function of organisms.

Explanation:

Nucleosomes are the basic unit of compaction of DNA. Each nucleosome is composed of ~148 bp double-stranded DNA and an octamer of histone proteins, which include two molecules of each core histone: H2A, H2B, H3 and H4. Subsequently, nucleosomes are packaged into chromatin fibers so they can be densely compacted into chromosomes. On the other hand, proteins are molecules that play important (structural and enzymatic) functions in a cell. These proteins may affect the structure/function of a cell, thereby affecting a certain characteristic/trait to develop.

Answers

Answer:

guard cells chloroplasts , involved in the photosynthesis where epidermal cells are living cells covering the outside surface of the herbaceous plants they contain a thick covering of cutting which reduces the water loss from Plants epidermal cells in roots are specialized for water and ion absorption don't know if it helped but good luck

Photosynthesis

The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. The upper and lower epidermal cells do not have chloroplasts, thus photosynthesis does not occur there.

Difference in guard and epidermal Cells:

Two guard cells form a stoma, controlling the gas exchange of the plant by regulating the size of the stoma whereas epidermal cells provide a protection to the plant from the external environment.

Photosynthesis does not take place in epidermal cell because:

The epidermal cells that make up this skin are transparent. As most epidermal cells lack chloroplasts, they can't perform photosynthesis, or the use of sunlight to convert carbon dioxide and water into glucose and oxygen.

Answers

Answer:

D. 367

Explanation:

If a roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates, it contains 367 calories of energy, hence option D is correct.

What is food energy?

Animals obtain the chemical energy known as "food energy" from their food in order to maintain their metabolism, which includes their muscular activity.

The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.

To find the total calories, multiply the given biomolecules grams with their calorie count.

= 42 × 4 + 7 × 9 + 34 × 4

= 168 + 63 + 136

= 367 calories

Therefore, the sandwich provides 367 calories of energy, if it contains 42 g protein, 7 g fat, and 34 g carbohydrates.

tRNA uses (anticodons/codons) to match to the mRNA.

Answers

Answer:

anticodons

Explanation:

codons are for mRNA

tRNA uses anticodons to match to the mRNA.

Which one does tRNA uses?

tRNA (transfer RNA) molecules are responsible for carrying specific amino acids to the ribosomes during protein synthesis.

They have an anticodon region that consists of three nucleotides that are complementary to the codons on the mRNA (messenger RNA). The codons on the mRNA determine the sequence of amino acids in the growing polypeptide chain.

The anticodon on the tRNA base pairs with the complementary codon on the mRNA, ensuring that the correct amino acid is incorporated into the growing protein chain. The matching between the anticodon and codon is essential for the accurate translation of genetic information into protein synthesis.

When a lake freezes over. How does the energy content of the lake change?

Answers

Answer:

Explanation:The remaining air (air that does not descend at 30 degrees North or South latitude) continues toward the poles and is known as the westerly winds, or westerlies

Question: How do ocean currents affect the coastal regions of S.America at 20 degrees south latitudeAnswer: Warm and cold ocean currents can affect the climate of an area along the coast if the winds blow in from the ocean. Warm ocean currents heat the air above the water and carry the warm air to the land, increasing the temperature of the coastal regionQuestion: When a lake freezes over. How does the energy content of the lake change? Answer: Liquid water has more energy than frozen water. When water freezes it gives up some of the water's energy. This energy that is given up is the latent heat of freezing. When the water was freezing latent heat of freezing energy was being released(WATER IS THE LAKE)Bonus: I know that during melting, there is no temperature change as the heat energy is used to do work against potential bond energy but why doesn't temperature change when freezing? Freezing is the opposite process of melting. If the temperature does not increase as the ice melts, the temperature will not decrease as water freezes. Melting and freezing are entropy changes. Entropy measure the amount of disorder in a system. A system, like ice, which has less freedom of motion, has less disorder. A system, like liquid water, which has more freedom of motion, has more disorder. So water has more entropy than ice. Ice is a very ordered arrangement of H2O molecules in a crystalline form. As heat energy is added to ice, the energy is used the break the bonds between the H2O molecules in the ice crystals. So, the temperature remains constant. You might say that the energy that is added to the ice is used to increase the entropy of the system, instead of increasing the temperature of the system.-TAY brainly please

Will give Brainliest within five minutes of answer - Why do we want to explore Mars more than the other planets/moons even though it is not currently habitable (with its temperatures, atmosphere, etc.)? How can it be habitable?

Answers

Answer:

After the Earth, Mars is the most habitable planet in our solar system due to several reasons:

Its soil contains water to extract

It isn’t too cold or too hot

There is enough sunlight to use solar panels

Gravity on Mars is 38% that of our Earth's, which is believed by many to be sufficient for the human body to adapt to

It has an atmosphere (albeit a thin one) that offers protection from cosmic and the Sun's radiation

The day/night rhythm is very similar to ours here on Earth: a Mars day is 24 hours, 39 minutes and 35 seconds

The only other two celestial bodies in orbits near the Earth are our Moon and Venus. There are far fewer vital resources on the Moon, and a Moon day takes a month. It also does not have an atmosphere to form a barrier against radiation. Venus is a veritable purgatory. The average temperature is over 400 degrees, the barometric pressure is that of 900 meters underwater on Earth, and the cherry on top comes in the form of occasional bouts of acid rain. It also has nights that last for 120 days. Humans cannot live on Mars without the help of technology, but compared to Venus it's paradise!

Additional info:

Mars is an obvious target for exploration because it is close by in our Solar System, but there are many more reasons to explore the Red Planet. The scientific reasons for going to Mars can be summarised by the search for life, understanding the surface and the planet’s evolution, and preparing for future human exploration.

Searching for life on Mars

Understanding whether life existed elsewhere in the Universe beyond Earth is a fundamental question of humankind. Mars is an excellent place to investigate this question because it is the most similar planet to Earth in the Solar System. Evidence suggests that Mars was once full of water, warmer and had a thicker atmosphere, offering a potentially habitable environment.

Natural selection is an outdated theory to explain how evolution took place. C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce. D. Natural selection is the process by which organisms develop variation in traits, which gives them a better chance of survival.

Answers

Answer:

C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.

Explanation:

Natural selection is an evolutional process by which species of living organisms with stronger or more beneficial traits have higher chances of survival and reproduction. In other words, it is the process by which organisms adapt and survive.

Organisms in a population are all different in their own ways. And those with characteristics or traits better suited for the environment are more likely to survive than those without. The selection prefers more beneficial traits and not wholly on the superiority of the organism. So, the survival and reproduction chance of an organism depends on the presence of traits beneficial to the environment, which is how nature selects. And in this process, those selected will dominate the population while those rejected will be reduced or even die.

Thus, the correct answer is option C.
