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)?

Answers

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.

A) CBDA
B) BACD
C) CADB
D) DBAC

Answers

The correct answer is C)

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.

"Draw a pedigree for hitchhiker’s thumb. Your pedigree should cover at least two generations and include both dominant and recessive forms of the trait. Label the pedigree with genotypes, using the letter H to represent the dominant allele for the trait and the letter h to represent the recessive allele."


I'm confused on the part about having two generations. How do I set up the pedigree?

Answers

Answer and Explanation:

First, you need to know how to interpret a pedigree representation.

Family members

→ Individuals are represented with geometrical figures.

→ Males are squares

→ Females are circles

Trait/Phenotype

→ Healthy/normal/not affected  individuals are represented with empty figures

→ Affected/mutated individuals are represented with solid black figures

Generations

→ Each file is represented with a roman number, indicating the Generation.

 

Now, what we need to do is to draw a pedigree for a hitchhiker’s thumb. We know that this is an autosomal dominant trait, which we will represent with an H. No hitchhiker's thumb is the recessive trait, and it will be represented with an h.

Our pedigree should cover at least two generations and include both dominant and recessive forms of the trait.    

We can cross two heterozygous individuals, Hh, who are the first generation in our pedigree. This cross will result in a woman and a man with No hitchhiker's thumb, another man with a hitchhiker's thumb, HH, and another woman with a hitchhiker's thumb, Hh. These individuals will represent the second generation in the pedigree. Finally, we can cross the man with No hitchhiker's thumb, hh, with a woman who does not have a hitchhiker's thumb either, hh. And the woman with a hitchhiker's thumb, Hh, with a man with a hitchhiker's thumb, HH. The result of these crosses will be the third generation.

The representation would be like following,

I → First-generation: First cross

Man Hh (1)  Woman Hh (2)

II → Second-Generation: F1 and second crosses

Man hh (3)  x    Woman hh (4)Woman hh (5)Man HH (6)Woman Hh  (7) x   Man HH (8)

III → Third-Generation:

A boy (9) and a girl (10) hhA girl (11) HH

You will find this pedigree in the attached files. In this example, we included three generations. The first one belongs to the grandparents, the second one to parents, aunts/uncles, and the third one to grandchildren.  

If you draw another pedigree, remember to include

the figures representing males and females, color and H/h representing the phenotype, Roman numbers representing the generations, and optional, numbers naming each member.

What is environmental sustainability in agriculture? Name four factors that are required for environmental sustainability in agriculture

Answers

Answer:

The correct answer is - without compromising climate health and providing social equity and agriculture needs.

Explanation:

Environmental sustainability in agriculture means farming in a sustainable way to provide the required needs of society such as food and textile etc without harming or compromising the environmental health for future generations. This type of agriculture practice involves various factors including following:

-Managing water wisely,

- Maintaining healthy soil,-

- Minimizing air, chemical use, water pollution.

- Nutrients and organic fertilizers

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

Answers

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.

Answer:

A

Explanation:

A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
