1.3
Explanation:
Density equals mass divided by volume. the mass of the cork is 5.7 and its volume(the amount of water it displaced) is 23.5 so [tex]\frac{5.7}{23.5} = 0.24[/tex]
the mass of the granite block is 2700. the formula to get the volume of a rectangular prism is Volume = length × width × height so 20 × 5 × 10 = 1000
Density equals mass divided by volume so [tex]\frac{2700}{1000} = 2.7[/tex]
Density equals mass divided by volume. the pipes mass is 78 and its volume is 60(amount of water displaced) so [tex]\frac{78}{60} = 1.3[/tex]

if the mountaineers without any suit travels to the mountain they will bleed why
Answer:
Air pressure goes on decreasing as we go higher up, so at high altitudes, the atmospheric pressure becomes less than the pressure exerted by the blood inside the body. This causes some of the blood vessels burst and the nose starts bleeding.
How do the roles fulfilled by the female lions increase the survival of the species?
Answer:
Lions and lionesses play different roles in the life of the pride. The lionesses work together to hunt and help rear the cubs. This allows them to get the most from their hard work, keeping them healthier and safer. During hunting, smaller females chase the prey toward the center of the hunting group.
Explanation:
How might an environment different from the one you experienced have affected the development of personality characteristics that you believe you inherited from one or both of your parents?
Answer:
The environment has a great impact on our behavior and personality traits which were believed to be inherited from the parents.
Explanation:
Each of the parents contributes 50% of the offspring DNA, and your inherited genetic makeup may have an impact on your personality. It is frequently asserted that our environment has a greater influence on our personality than our genetics. The adaptability of our capacities, cognitive abilities, and social interests accounts for a large part of our personality. Only via our interactions with our surroundings can we gain the flexibility that forms us.
Yes, our genes are passed down to us, yet it has been proposed that they have no bearing on our behavior.
As a result, a kid is born into a situation that prompts them to react as specified in birth order stereotypes, and therefore our personality has been shaped by our surroundings. However, there is little scientific evidence to back up this theory, therefore it's possible that personality is determined by genetics.

How did the agricultural revolution change the environment?
The agricultural revolution negatively affected environments by destroying natural wild habitats and by releasing important carbon dioxide emissions (CO2) into the atmosphere.
The Agricultural Revolution refers to the increase in agricultural production in terrestrial areas, which occurred during 1750-1850.This revolution has led to the destruction of natural habitats by deforestation, thereby decreasing biodiversity in terrestrial ecosystems.The Agricultural Revolution has also been associated with an increased release of CO2 into the atmosphere, a greenhouse gas that contributes to global warming.Learn more in:

Many populations exhibit the following growth curve.
Which statement(s) below accurately are describing the growth as shown on the graph. NOTE: There is MORE THAN ONE correct answer. Choose ALL that apply.
Select 3 correct answer(s)
Question 5 options:
Phase B of the graph is showing a population that has reached its carrying capacity.
When both phases of the graph are looked at together, it shows logistical growth of a population after growing exponentially and reaching its carrying capacity .
Phase B of the graph is showing exponential growth only.
The entire graph shows two organisms competing for space.
Phase A of the graph is showing exponential growth only.
Many populations exhibit the following growth curve.. Here option 1, 2, 3 are correct which describe the growth. Phase B of the graph is showing a population that has reached its carrying capacity.
What is carrying capacity ?
The carrying capacity of the individual is the maximum number of population size of the species in a sustainable environment which is indefinitely reach up to the limit of no further growth.
Carrying refers to support and Capacity means it is the ability of an organism to reproduce the maximum output, when population reaches the limit of carrying capacity then the mortality will be greater than natality.
The importance of Carrying capacity is mainly focused on the concept of sustainability, imbalance in the environmental and Global warming which are the causative agent, eradication of poverty and practices are also increase the importance of carrying capacity.

Suggest possible effects on a child of the pituitary gland producing unusually high amounts of these hormones.
!!Don't answer this ques if u don't know the answer!!
Answer:
Too Much Growth Hormone in a Child: Causes and Effects
Growth hormones are important influences on a child’s height and development. While many children are shorter or taller than others due to genetics, some children may have a growth disorder.
Growth disorders affect the speed at which a child develops. Height, weight, and sexual development are just a few features which can be affected. Diseases or problems with the pituitary gland are the leading causes of growth disorders.
The pituitary gland is responsible for producing growth hormones. Too few can lead to poor growth in children, while too many can lead to a condition called gigantism.
