Answer:
The development of the embryo is what Dawkins means that is performed by the local rules on the cellular level in terms of internal chemistry and tissue development. A small and local unit present in the human body that follows the rules of the on the particular scale.
Dawkins explains that development that various tissues develop and controls other cellular responses during the development of the embryo is in progress. He also suggested that differentiation of the cells is asymmetric cell division.

a. anaerobic metabolism
b. lactic acid metabolism
c. aerobic metabolism
Answer:
The correct answer is a. anaerobic metabolism.
Explanation:
Anaerobic metabolism refers to a high intensity of exercise in which the absence of oxygen limits performance due to the accumulation of metabolites and the corresponding metabolic and physiological dysregulation.Predominantly anaerobic exercises are characterized by: high intensity and short duration, energy is obtained from immediate sources such as muscle ATP, phosphocreatine (PC) and glucose and does not need oxygen for this. For very explosive or high intensity movements it is necessary to obtain a powerful and fast energy, this is obtained by anaerobic systems. The anaerobic metabolism is able to respond immediately to the energy demands of physical exercise and can provide energy for very high intensity exercises (strength and / or power). But this system has a limited capacity, it is short-lived, so if the exercise continues, either you have to stop due to fatigue or reduce its intensity (the power developed) to a level where energy can be obtained through the aerobic metabolism.

The hypothalamus regulates the ________.
a. thalamus
b. pineal gland
c. pituitary gland
d. pons
Answer:
c. pituitary gland
Explanation:
The hypo(below) thalamus is an almond size structure located superiorly to the brainstem. it is located below the thalamus. Hence the name hypothalamus.
It is primary function is is to control the body homeostatic functions of sleeping and waking up, sex, thirst and hunger etc.
It performs these roles by serving as the primary link of the nervous system with the endocrine system. Pituitary gland is an example of endocrine gland that secrets many hormones. (they are called endocrine because the hormones are secreted directly into the blood streams.
Its activities are controlled by the nervous stimulation from hypothalamus. Therefore the instructions to secretes certain hormones to the post and anterior part of the pituitary gland depends on the hypothalamus.
Growth hormones, oestrogen, and thyroid are examples of hormones of the pituitary glands.

What affect does the Sahel's climate and physical characteristics have on population distribution?
Answer:
The Sahel has been labeled as one of those regions with the danger of overpopulation. It has been described with adjectives such as semi-arid, hot, dry, windy or sunny.
Sources have it that the G5 Sahel countries which include Mali, Niger, Burkina Faso, Mauritania, Chad will increase from about 84 million inhabitants in 2019 to 197 million in 2050. This projection includes people under 15 years of age which comprise about 50% of the entire population.
The climate itself doesn't seem to deter population growth. What seems to be occurring is sedentarization. This is due to rapid desertification and drought which have persisted for some time.
Explanation:
Sedentarization refers to the choice of a group of people who usually are very nomadic or migratory to settle permanently in a place.
This is usually due to a more favorable weather and topography which supports agriculture.

HELP PLS, AND EXPLAIN, I BEG: Nancy needs to do a scientific investigation for her class. She is interested in pottery, plants, and basketball. Which of the following questions would be suitable for use in a scientific investigation?
A. What length of time is best to use for the firing of pottery to make it strong?
B. How many needles grow on the giant redwoods in California?
C. What color of carnation flowers do people find most attractive?
D. What is the most number of points ever scored in a professional basketball game?
Answer:
A. What length of time is best to use for the firing of pottery to make it strong?
Explanation:
Point A
What length of time is best to use for the firing of pottery to make it strong?
This is a scientific question for Nancy since while making pots from black mud, it is very important to know how much time is required to fire the pot in order to make it strong. Because if we fire it for too long the pot may be become too hot and will eventually crack. While if we fire for less time it will not become hard enough to withstand its shape. So knowing the proper time to fire the pot is very essential in pottery.
Point B, Point C and Point D are not scientific investigations since it includes ones likes and dislikes, quantities and numbers of goal scored which is not scientific.
Hence, option A is the correct answer.
While their unique evolutionary paths have led to different adaptations, non-vascular and vascular plants are commonly found occupying similar habitats and together play an important role in establishing community structure and biodiversity. Compare and contrast how they interact together in this particular ecosystem, and the role their unique adaptations have played in forming the above relationships (Compare and contrast at least 2 relationships). What happens to these interactionsifwe lose just one species
Answer:
Non-vascular plants provide nutrients, avoid erosion and habitat to animals.
Explanation:
Non-vascular plants has played an important role in the ecosystem and biodiversity because it releases various nutrients in the soil which can be used by the vascular plants from the soil and also reduce erosion of the soil. These non-vascular plants provides habitat and food to various animals in the ecosystem. If the non-vascular plants can be removed from the ecosystem, the whole ecosystem will be disturbed and adverse effect on vascular plants and animals occur.
In humans, freckles are a trait that exhibits simple dominance. The two alleles for this trait are freckles (A) and no freckles (a). A freckled man whose mother has no freckles marries a woman with no freckles. What is the probability that their first child will have freckles? Use the Punnett square to show your work.
Answer:
50 percent
Explanation:
Aa goes with aa
so their children's genotypes would be
Aa Aa aa and aa
so two with freckles and two without freckles which is why their first child has a 505 chance of having freckles
hope this helps :)
The probability of having a freckled child is 50%. because half of the children will have the genotype Aa, which is freckled, and half will have the genotype aa, which is no freckles.
What is a punnett square?A Punnett square is a tool used to predict the probability of an offspring having a particular genotype (genetic makeup) based on the genotypes of its parents. To create a Punnett square, we use the alleles of the parents and place them into a grid, with one allele from one parent on the top and the other allele from the other parent on the left-hand side.
In this scenario, the father has a genotype of Aa (freckled) and the mother has a genotype of aa (no freckles). The mother only has the recessive allele (a) and the father has both dominant (A) and recessive (a) allele.
The probability of having a freckled child is 50%. because half of the children will have the genotype Aa, which is freckled, and half will have the genotype aa, which is no freckles. The dominant A allele will mask the recessive a allele and make the offspring freckled.

why does breathing rate increase during excercise?
Answer:
When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.

According to the Janzen-Connell hypothesis, in order for pathogens or herbivores to contribute to the maintenance of diversity: Select all that apply. the pathogens/herbivores must be host-specific. mortality of seedlings due to competition between plants must be less important than mortality due to herbivores/pathogens. the infections must be avirulent. the pathogens/herbivores must result in lower seedling mortality close to adult plants of the same species.
Answer:
The correct answer is -
The pathogens/herbivores must be host-specific.
Mortality of seedlings due to competition between plants must be less important than mortality due to herbivores/pathogens.
Explanation:
According to the Janzen-Connell hypothesis, it is showed by research that seeds of rare species are more likely to escape seed from herbivores/pathogens. According to this theory, pathogens should be able to infect only a specific species.
Competition is less important in terms of mortality of seeds than it is due to the predators such as herbivores/pathogens of a species according to this hypothesis.
