Jorge is testing the effect of lead on child development. Based on his observations, he finds that the longer the children are exposed to lead-based paint, the higher the chance becomes that the children may develop behavioral problems. He has done repeated experiments, and his results are similar to the results of many other scientists.

Black bears in the north hibernate mostly due to the scarcity of food during the winter months.
Prior to hibernation bears are foraging for food. They eat fruit, nuts, acorns, insects, and certain leaves and plants. They catch occasional small animals, but lack agility to catch most adult prey. In the months before hibernation black bears can gain up to forty pounds of fat per week.
9. What types of food molecules is the bear consuming (give at least two)?
Answer:
Food having high fat.
Explanation:
The bear eat food products having high fats in order to store it in the body. The food which have large amount of protein and fats are stored in the body and helps in gaining of weight up to forty pounds of fats per week. During hibernation period, bear used this fats for the release of energy used for its survival. Fats produce huge amount of energy when they are broken down so this fats helps in hibernation of bear.

Which statement best describes the starch content of two leaves taken from the same plant shown in the
chart below?
leaf A
taken from plant in
the dark for 48 hours
leaf B
taken from plant in
bright light for 48 hours
(1) Neither leaf contains starch.
(2) Both leaves contain the same amount of starch.
(3) Leaf A contains more starch than leaf B.
(4) Leaf B contains more starch than leaf A.
The statement best describes the starch content of two leaves taken from the same plant shown in the chart is given: (4) Leaf B contains more starch than leaf A.
Dark reactionplants use carbon dioxide with ATP and NADPH from the light reactions to produce glucose.It takes place in the stroma of the chloroplast.Light reactionsThe energy is then temporarily transferred to two molecules, ATP and NADPHThe light reaction is important to produce ATP and NADPH which is used as fuel for starch production.Thus, The statement best describes the starch content of two leaves taken from the same plant shown in the chart is given: (4) Leaf B contains more starch than leaf A.

The _____ of a species is usually the result of predation, competition, and other types of interaction between species.
Answer: Realized Niche
Explanation:
Realized niche is also referred to as Post Competitive niche and can be defined as a thriving environmental area created by a group of organisms to survive from an exsisting Faundermental niche where interactions (predation, competition, light, water,food) with other organisms were limited and competed for.
For example. In a tree( Faundermental niche) which houses different species of birds, In order to survive, each specie of the birds will create a realized niche so as to survive from predation, competition, light etc which the whole tree provides.

Which list identifies the order of events that formed a volcanic crater?
A) CBDA
B) BACD
C) CADB
D) DBAC
Based on the given image, the order of events that formed a volcanic crater is CADB. Thus the correct option is C.
What is a volcanic crater?A nearly circular hole in the ground produced on by volcanic eruptions is known as a volcanic crater. It is a valley that typically stands just above the eruption where volcanic debris is emitted, and it has the shape of a bowl or funnel.
During volcanoes, craters' dimensions and shapes could alter. A volcanic crater, also known as a caldera, is a sizable depression created when a natural disaster occurs and then collapses.
Underneath the surface of the Earth, the molten rock is known as magma. Less dense than normal lava is being pushed upward to the surface by intense pressure. When magma seeps through layers of preexisting rock, it forms another structure.
Therefore, option C is appropriate.

Scientists in Brazil have developed specific fertilizers and special breeds of soybeans and corn so crops can grow on large areas of tropical lands. This is valuable because farmers can help to feed the growing human population and strengthen the economy. However, trade-offs must be considered because farming on tropical lands can also A add helpful microorganisms to the soil B remove oxygen from the atmosphere C reduce populations of native species D reduce mutations and disease in wildlife populations
Answer:
C reduce populations of native species
Explanation:
The overexploitation of the land by farming practices represents one of the most important challenges that face wild populations and threatened species, representing a concern to biodiversity conservation. Farming practices can destroy the natural structure of the soil, reducing diversity by killing small animals (e.g., insects), bacteria, and fungi that live in the substrate. Moreover, runoff may also carry herbicides and pesticides used in monocultures that can damage aquatic ecosystems, disrupting and killing aquatic wildlife and polluting water sources. Some ecological farming methods that help to reduce biodiversity loss include, among others, the use of natural fertilizers, diversification of crops, biological pest control, etc.
