2. No, the Earth is roughly a sphere.
Explanation:
Brainliest?
Answer and Explanation:
1. Water is wet. This is because the water molecules cover each other and come in contact, making them wet. A water molecule by itself with no other molecules is not wet.
2. The Earth is NOT flat. This is because during lunar eclipses (when the Earth’s orbit places it directly between the Sun and the Moon, creating a shadow in the process), the shadow on the Moon’s surface is round. This shadow is the planet’s, which means that the Earth is spherical.

Answers
Mitochondria evolved from aerobic bacteria while chloroplasts evolved from cyanobacteria.
Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. A eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.
Chloroplast evolutionarily derives from a primitive cyanobacteria that was engulfed by non-photosynthetic cells and, progressively, after losing most of its DNA, became the actual chloroplast that retains only a fraction of the original cyanobacterial genes. Chloroplasts of plants and algae are currently believed to originate from a cyanobacterial endosymbiont.

Answer: BO YOUR LAZY!
Explanation:
For decades scientists have been perplexed by different circumstances surrounding families with rare, early-onset auditory neuropathy (deafness). In some families, parents and grandparents of the proband have normal hearing, while in other families, a number of affected (deaf) family members are scattered throughout the pedigree, appearing in every generation.
Required:
Assuming a genetic cause for each case, offer a reasonable explanation for the genetic origin of such deafness in the two types of families.
Answers
Deafness in the two types of families occurs through a recessive gene.
What Heredity?Heredity is the transmission of inherited characters from parents to offspring through the genes.
Inherited traits may be due to dominant or recessive genes.
Triats inherited through dominant genes are always expressed in every generation.
Triats inherited through recessive genes do not always appear one every generation.
Since deafness appears in some members of the family and not in others, it means that deafness is inherited through recessive genes.

Which statement best summarizes the temperature pattern shown in the
weather map?
A. Temperatures increase from the southeast to the northwest
B. Temperatures decrease from the southwest to the northeast.
C. Temperatures increase from the southwest to the northeast.
D. Temperatures decrease from the northeast to the northwest.
Answers
Answer:
B
Explanation:
Darker colors such as red and orange represent warmer temperatures and lighter colors such as green represent cooler temperatures
Northeastern USA has a lot of lighter colors meaning that it's cooler in the northeast
Southwestern USA has a lot of darker colors meaning that its warmer in the Southwest.
If you were to draw from southwest to north east temperatures would decrease as it's cooler in the northeastern areas.
Therefore we can conclude that B is the correct answer.

b. mean that sponges must no longer be classified as animals.
c. confirm the identity of sponges as "basal animals."
d. mean that extinct sponges must have been the last common ancestor of animals and fungi.
e. require sponges to be reclassified as choanoflagellates.
Answers
Answer:
c. confirm the identity of sponges as "basal animals."
Explanation:
Homeotic genes (also known as homeobox genes) are genes that encode major transcription factors found in divergent species ranging from animals to plants. These genes contain an evolutionarily conserved sequence (homeobox sequence) that encodes a 60-amino acid DNA-binding domain (homeodomain) found in major transcription factors that interact with DNA and thus control body patterning during development of plants and animals. Moreover, Hox genes are a subset of homeotic genes only found in bilaterian animals that have arisen more recently in evolution. In animal embryo development, Hox genes control the body pattern along the head–tail axis.
In homeostasis, what is it that produces the response that moves the physiological variable back towards the middle of its healthy range?

There is a small amount of NAD+ made by a cell. If oxygen is not present, pyruvate becomes the final electron acceptor thus allowing for the recycling of NAD+.
QUESTION: EXPLAIN how using pyruvate as the final electron acceptor in an anaerobic process allows for the recycling of NAD+.
Answers
Claim: Using pyruvate as the final electron acceptor in an anaerobic process allows for the recycling of NAD+.
What are the evidence and reasoning?Evidence: During anaerobic respiration, the breakdown of glucose begins with glycolysis. In this process, glucose is broken down into two pyruvate molecules, which also generate ATP and NADH.
Under anaerobic conditions, pyruvate becomes the final electron acceptor instead of oxygen. Pyruvate is then converted to lactate or ethanol and CO2, which regenerates NAD+ from NADH.
Reasoning: In the absence of oxygen, cells rely on anaerobic respiration to generate energy. During glycolysis, glucose is broken down into pyruvate, which generates a net of two ATP molecules and two NADH molecules. In order for glycolysis to continue, NADH must be recycled back to NAD+.
However, without oxygen, the electron transport chain cannot occur, and the NADH cannot be oxidized. Instead, pyruvate acts as an alternative electron acceptor, which is converted to lactate or ethanol and CO2. This reaction allows NADH to transfer its electrons to pyruvate, regenerating NAD+ in the process. As a result, glycolysis can continue to generate ATP, and the cell can survive under anaerobic conditions.

Leptosporangiate ferns are a group of ferns that produce small, compact sporangia that contain spores. Sporangia are typically located on the underside of fertile leaves, grouped together in structures called sori. The sori are usually round or elongated and can vary in size depending on the species of fern.
In Leptosporangiate ferns, sporangia are small structures with a wall that is a single cell layer thick.

Check all that are true of the following scenario.
An archer strings an arrow on a bow and draws the string back. Aiming the bow
upwards at a 45 degree angle, the archer pauses with arms locked into position and
then releases the string. The arrow flies upwards making an arc and then sticks into
the trunk of a tree with an audible thud.
At least four different types of energy are illustrated in this example.
The first energy transformation in the scenario is chemical energy to kinetic.
From the time the archer draws the bow until the thud us heard, entropy increases in
the universe.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the
muscles of the archer.
When the arrow sticks into the tree the original energy has all been used up.
Answers
Statements 1 and 3 are true, while statements 2 and 4 are false.The first energy transformation in the scenario is chemical energy to kinetic. - True.
The archer converts chemical energy stored in their muscles into kinetic energy when they release the string and propel the arrow forward.From the time the archer draws the bow until the thud is heard, entropy increases in the universe. - False. Entropy is a measure of disorder or randomness in a system. In this scenario, the archer's actions do not necessarily lead to an increase in entropy.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the muscles of the archer. - False. Energy is conserved in a closed system, but some energy is lost as heat and sound during the process. Therefore, the energy of the arrow at the end may be less than the energy exerted by the archer's muscles.
When the arrow sticks into the tree, the original energy has all been used up. - False. Energy is not created or destroyed but rather transformed from one form to another. Some of the initial energy from the archer's muscles is transferred to the arrow's kinetic energy, but it is not entirely used up.In summary, statements 1 and 3 are true, while statements 2 and 4 are false.
