Two humans mate who are heterozygous for earlobe shape where attached earlobes (A) are dominant to free earlobes (a), and earwax quality where dry earwax (e) is recessive to wet earwax (E ). What is the probability that their first child will have dry earwax and attached earlobes
Answer:
3/16
Explanation:
This question involves two different genes coding for earlobe shape and earwax quality. The alleles for attached earlobes (A) and wet earwax (E) are dominant over the alleles for free earlobes (a) and dry earwax (e).
According to this question, two humans mate who are heterozygous for both genes i.e. AaEe × AeEe. Each parent will produce the following gametes: AE, Ae, aE, ae.
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
* Attached earlobe, wet earwax (A_E_) = 9/16
* Attached earlobe, dry earwax (A_ee) = 3/16
* Free earlobe, wet earwax (aaE_) = 3/16
* Free earlobe, dry earwax (aaee) = 1/16
Hence, the probability of these parents having their first child with dry earwax (ee) and attached earlobes (A_) i.e. genotype A_ee is 3/16.

Explain how natural selection can impact allele frequencies (amount of traits seen) of a population
Answer:
Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population. ... Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).

What factors influence the survival of Kangaroos in its natural habitat?
Answer:
Kangaroos from desert and semi-arid environments have adapted to drier conditions and have several features that help them deal with the lack of water. Kangaroos need very little water to survive. Kangaroos hop over large distances to find food and water. Hopping is a fast, energy efficient way to travel. Kangaroos need very little water to survive and are capable of going for months without drinking at all. The kangaroo usually rests in the shade during the day and comes out to eat in the late afternoon and night when its much cooler. It eats mostly grass. It needs very little water to survive.

how might biotic and abiotic factors have affected the tortoises that Darwin observed on the Islands
Answer:
Some Abiotic factors are water, soil, light, temperature. These are non-living things that the tortoises will interact with in the enviornment. These can affect them for example if there is an abundance of water and light then the tortoise population can expand. However if there is too little or too much of these factors then the population will decrease. Biotic factors are plants, animals, bacteria and Protists. These are the living things the tortoises will interact with in the enviornment. Biotic factors can affect them for example if there are too many preditor animals for the tortoises, then their population will be very low and a lot of them will die.
Explanation:
Some Abiotic elements are water, soil, mild, temperature. These are non-residing matters that the tortoises will have interaction with withinside the environment.
These can have an effect on them for example if there may be an abundance of water and mild then the tortoise populace can expand. However, if there may be too little or an excessive amount of those elements then the populace will decrease. Biotic elements are flora, animals, microorganisms,s, and Protists. These are the residing matters the tortoises will have interaction with withinside the environment.What did darwin find on the islands?
He found out that the tortoises had tendencies that allowed them to stay in their precise environments. For example, tortoises that ate flora close to the floor had rounded shells and shorter necks.
Thus it is clear that biotic and abiotic factors have affected the tortoises that Darwin observed on the Islands.

Explanation:
Hope this helps :)
The youngest fossils are pollen grains, which are in Option A, and these youngest fossils are typically found in sedimentary rocks and can vary in age depending on the type of fossil.
What are the "Youngest fossils" fossils?"Youngest fossils" can refer to fossils that are relatively recent in geological time, an example of the youngest fossils is those of the Holocene epoch, which is the current geological epoch that began around 11,700 years ago. This epoch is characterized by a warmer climate and the rise of human civilization, animal and plant remains aside, the youngest fossils can also include remains of human ancestors, such as Neanderthals, whose fossils have been found in Europe and parts of Asia.

HOW DO THE OCEANS CURRENTS AFFECT CLIMATE
Answer:
Explanation:
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.

One explanation for why our sense of smell and language are so disconnected is that
A. smell is only of secondary use to humans, language is of primary use.
B. olfactory information is not integrated in the the thalamus prior to processing in the cortex, and the two systems are primarily processed in opposite hemispheres.
C. there is no need to have connections between smell and language.
D. language developed much earlier in evolution than smell.
E. olfactory information is more widely distributed throughout the brain than is language.
Answer:
B. olfactory information is not integrated in the thalamus prior to processing in the cortex, and the two systems are primarily processed in opposite hemispheres.
Explanation:
The thalamus is the main source of sensory information to the primary sensory cortex except for the sense of smell. The olfactory information from the sensory neurons needs to pass through the thalamus in order to reach the primary sensory cortex. Moreover, different thalamic nuclei, i.e., different groups of packed neuronal cell bodies that form the thalamus, have been involved in language. A bilateral thalamic activation (with left greater than right thalamic activation), as well as the activation of cortical regions associated with the language, is observed during tasks related to language processing. Language information is processed within the left hemisphere, while the olfactory information is processed in the olfactory bulb which is located on the inferior (bottom) side of the cerebral hemispheres.

Explanation:
CORRECT me if I'm wrong.
#Carryonlearninh
If at start there are 60 chromosomes and ending with 30 chromosomes, then the process is meiosis. The correct option is C.
What is meiosis?Meiosis is a type of cell division that occurs in reproducing organisms and results in a reduction in the number of chromosomes in gametes (or egg and sperm).
Body (or somatic) cells in humans are diploid, with two sets of chromosomes (one from each parent).
Meiosis is a type of cell division that produces four gamete cells while reducing the number of chromosomes in the parent cell by half.
This process is necessary for the production of egg and sperm cells for reproduction.
Without meiosis, the number of chromosomes in a species does not remain constant across generations and is duplicated every time after reproduction.
Without meiosis, an organism cannot reproduce effectively through reproduction.
As, meiosis is equational division, and the chromosome number is also getting reduced to half, it can be meiosis.

What is photosynthesis and it's effects?Photosynthesis is the process by which green plants that posses chlorophyll traps in energy from sunlight and uses it to convert solar energy to chemical energy which is the form of energy that is useful for living organisms.
This is carried out by the absorption of light by the green pigment, chlorophyll. This helps in the splitting of water molecules which further react with carbon dioxide to form sugar
Therefore, the amount of energy that is used up during photosynthesis changes to a lesser amount of chemical energy because of the sugar that is produced as by product.
