option (a)

Explanation:

Kidneys remove waste products from the blood and produce urine

Answer:

reptiles have similar to the bird.

Final answer:

Members of the same species have the highest DNA similarity and organisms with a more recent common ancestor share more DNA sequences in common. Comparison of DNA among different organism pairs shows varying degrees of molecular differences based on the time since their evolutionary split. A bird is genetically closer to another bird species due to shared evolutionary history.

Explanation:

The organism that would have DNA most similar to a bird is likely another bird species due to the homologous structures and genetic similarities they share, illustrating a close evolutionary relationship. Broadly speaking, members of the same species have the highest level of DNA alignment. In contrast, organisms that diverged earlier in evolutionary history, such as a bird and a mammal, would have more significant molecular differences in their DNA. Hence, when comparing DNA similarities among various organisms, the evolutionary timeline is a critical factor. Comparisons between a mammal and a bird, a mammal, and a frog, or a mammal and a fish would reveal increasingly significant differences the further back the common ancestor existed.

For instance, a whale would share more DNA sequences with a horse than with a shark, even though sharks may appear more similar to whales due to their aquatic environments. This is because whales and horses are both mammals, whereas sharks are fish, and the evolutionary split between mammals and fish occurred much earlier.

Answer: Silent mutation

Explanation: Silent mutation do not result in a change of amino acid. This is because some amino acids have more than one codon that code for them. For example a change from TTT to TTC will still result to leucine

The statement that accurately correlates stages of hominid evolution is that the brain increased in size, leading to the development of tools.

The correct statement that makes an accurate correlation between stages of hominid evolution is b) The brain increased in size which resulted in hominids developing tools.

This statement reflects the correlation between the increase in brain size and the development of tools in hominids. As the brain size increased over time, it allowed hominids to develop the cognitive abilities necessary to create and use tools. This development in tool-making skills played a crucial role in the success and adaptability of hominids in their environment.

In contrast, the other options are inaccurate. The brain did not decrease in size during hominid evolution, and there is no direct correlation between the decrease in brain size and the increase in skull size. Additionally, while language development is believed to be linked to brain size and cognitive abilities, it is not directly related to the size of the skull.

Explanation:

A fungus is a decomposer.

Answer:

part of the brain that controls muscles

Explanation:

It affects movement, balance, and muscle tone leading to rigidity in the joints, involuntary movements, and exaggerated reflexes.

The left hemisphere of the cerebral cortex is likely affected in an individual with cerebral palsy who experiences movement problems in their right arm and hand due to the contralateral nature of motor control. Damage to areas such as the precentral gyrus can lead to such motor impairments.

Individuals with cerebral palsy (CP) usually have movement difficulties due to brain injury sustained before, during, or shortly after birth. The brain regions responsible for the control of body movements are affected, and the symptoms can range from mild muscle weakness to severe motor disabilities. Specifically, if a person with cerebral palsy has movement problems in their right arm and hand, the area likely affected is located in the left hemisphere of the cerebral cortex.

This inference is because the motor control of each side of the body is governed by the opposite side of the brain due to the cross-wiring of the corticospinal tract. Commands for motor movement are issued by the precentral gyrus, commonly known as the primary motor cortex, which is in the left hemisphere for the control of the right side of the body in about 95% of the population. Considering the non-progressive and permanent nature of the postural and movement disorders in cerebral palsy, interventions often focus on rehabilitation to improve or maintain motor function and coordination.

Explanation:

.Since in solids (such as packed earth) molecules are packed more closely together than in gases (such as air), the speed of sound waves should be faster in solids than in gases.

Answer:

B. Particles of matter are packed moe tightly in the ground than in the air.

Explanation:

The correct answer is

b. Particles of matter are packed more tightly in the ground than in the air.

Sound waves generally move faster in solids than liquids and gases. The reason is that sound waves are vibrations of the molecules of the medium: therefore, if the particles of the medium are closer together (as in solids), the vibrations can be transmitted faster, and the wave can travel faster. On the contrary, in gases the particles are spread apart, so the vibrations are not transmitted so easily (because there are less collisions between the particles) and the wave travels slower.

The characteristics of Zygomycota are spores produced in zygosporangia and important in the fermentation process. Therefore, options 3 and 5 are correct.

The Phylum Zygomycota contains a relatively tiny group of zygomycetes, which are part of the fungus kingdom. One of these is the well-known Rhizopus stolonifer bread mold, which spreads quickly on the surfaces of bread, fruits, and vegetables. They primarily live on land, either in soil or on other plants and animals.

They reproduce by means of sexual reproduction through the formation of zygospores. They are used in the process of fermentation.

Answer:

Mustn't.

Explanation:

Children in this picture are been labelled pedestrians, and it is totally wrong to use the zebra/white road crossing. This is because their are signs for pedestrians which is pedestrian crossing which is suggestive on when to move or halt totally.

In the other words, the red light means to halt totally while the amber means ready while the green signals move; but these all applies to auto operators or bike and motorcyclists. So the children mustn't cross until the pedestrian walk is signalled for movement on it.

Traffic light colors are of different types with their usual meaning.

Red light means the vehicles should stop while the pedestrian can move.

Greenlight means the vehicles should move while the pedestrian should stop. Yellow light means "ready to move"

According to the given question, we can say that "Children, you must  cross the street if the lights are red!. Since red represents that the vehicles are not moving, hence the children are safe to cross the road.

Answer:

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

Explanation:

Final answer:

The correct order of mitosis stages is prophase, prometaphase, metaphase, anaphase, and telophase, crucial for ensuring accurate DNA replication and division into daughter cells. DNA replication occurs during the S phase of interphase, before mitosis.

Explanation:

The question inquires about the correct sequence of events during mitosis. Mitosis is a critical process of cell division that ensures the daughter cells receive an exact copy of the parent cell's DNA. The phases of mitosis progress as follows: prophase, prometaphase, metaphase, anaphase, and telophase, followed by cytokinesis. Observations reveal that DNA synthesis, a precursor to this process, occurs during interphase, ensuring that each daughter cell receives a complete set of chromosomes.
