Vegetable farmers often plant soybeans every few years. Rotating crops breaks up the life cycles of many insect pests, and the soybean plants provide the soil with nitrogen. Other crop plants need the nitrogen to grow well. A field of soybean seeds has been planted on a farm in Indiana. As soon as the first leaves emerge from the seed, photosynthesis begins. Which substance is the chemical food source for the soybean plants? A. sunlight
B. Glucose
C. Carbon Dioxide
D. Water

Answers

The glucose is the chemical food source for the soybean plants. The correct option is B.

What is glucose?

Glucose, also known as dextrose, is a type of carbohydrate known as a simple sugar, this can be found in both plants as well as animals.

The molecular formula for glucose is C_6H_1_2O_6. It is found in fruits and honey and is the most abundant free sugar in the blood of higher animals.

Plants use the sun's energy to convert water and carbon dioxide into glucose, a sugar.

Plants use glucose for energy and to make other substances such as cellulose and starch. Cellulose is used to form the basic cellwalls. Starch is stored as a food source in seeds and other plant parts.

The chemicalsource of food for the soybean plants is glucose as per the given scenario.

Thus, the correct option is B.

Explanation:

Initially, the myrtle warbler and Audubon's warbler were considered two different species. These birds have now been reclassified as eastern and western forms of a single species. Which of the following pieces of evidence would warrant this reclassification?. . A.The two forms interbreed successfully where their habitats overlap.. . B.The two forms live in habitats with similar terrain and temperatures.. . C.The two forms eat the same type of wood grubs and flying insects.. . D.The two forms display very similar physical traits such as coloration and tail-shape.

Answers

The Myrtle Warbler and the Audubon's warbler used to be considered two separate species. However, pieces of evidence warrants a reclassification of Eastern and Western forms of a single species. The reason for the reclassification is the two forms interbreed successfully where their habitats overlap. The correct answer is A. 

Answer:

Option A, The two forms interbreed successfully where their habitats overlap

Explanation:

The two species of warbler i.e myrtle warbler and Audubon's warbler are capable enough to interbreed when their  habitat overlap by maintaining postzygotic selection against hybrids.

These two warblers do not interbreed freely but they do so on routine basis in a narrow zone  at the northern edge of the Audubon form’s range in western Canada to hybridize

Hence option A is correct

2.) A scientist is testing the efficiency of various pH levels by measuring average growth rate. She runs 7 trials. What is the dependent variable of this experiment?a.) Plant Growth
b.) pH of Soil
c.) Average Plant Growth
d.) Type of Soil

Answers

I think it's B because in the question it says "she is testing the efficiency of various pH levels by measuring average growth rate". Also, keep in mind that dependent variable is what is being tested or measured in a scientific experiment. The growth of the plant would be independent variable because when testing for a independent variable it's the change or what's being controlled.

No matter what the cell type, prokaryotic or eukaryotic, plant or animal, the ____________ forms a protective barrier between the exterior environment and the interior of the cell.a. cell wall
b. cytoskeleton
c. cell membrane
d. glycoproteins

Answers

c. cell membrane forms a protective barrier between the exterior environment and the interior of the cell.

Cell membranes contain membrane proteins that allows all the interaction that occurs within the cell. It makes the cell membrane selectively permeable because of its characteristics as being fluid or its fluidity which means to say that they can move freely within the lipid bilayer. The membrane proteins can also be stored in the lipid bilayer together with the enzymes. It cannot be denied that membrane proteins have a lot of functions based on its type. They can be integral proteins, peripheral proteins and lipid bound proteins.



The most common example of shared characteristics among different types of cells is the cell membrane. Every cell is enclosed by a cell membrane which protects the cell from its surroundings by separating the interior components from the exterior ones.

Further Explanation:

A cell membrane is permeable to selective molecules which means only particular substances can traverse the membrane. The essential molecules are allowed to enter whereas the toxic or non-essential molecules are excreted out of the cell through the cell membrane.

The phospholipids are arranged in a bilayer to form a cell membrane. It also contains the cholesterol present in between phospholipids and maintains the fluidity at different temperatures. The membrane also contains integral and peripheral proteins that help in the transport of materials and maintain the structure and shape of the cell respectively. Glycoproteins are also attached covalently to the membrane and help in cell-cell recognition, cell adhesion, and also serve as receptors for other molecules.

Apart from the cell membrane, certain cells also contain cell walls which surround the cell membrane. It is present in plants, bacteria, and fungi and prevents the over-expansion of the cell. In plants, the cell wall helps in providing turgidity to the cell and also maintains the shape and structure of the cell whereas, humans are devoid of cell walls instead they contain cell membranes.

A cytoskeleton is not a protective barrier for the cell but provides rigidity to the cell and is present in the cytoplasm of the cell. Its main function to provide rigidity to the cell and resistance against deformation by associating with other proteins and connective tissues. It also helps in the transport of material within the cytoplasm and also helps in cell signaling.

Question 9.9. Which bone would a forensic anthropologist analyze to identify a victim as male or female?A. pelvis
B. tibia
C. humerus
D. sternum


Question 10.10. Which institution most likely employs a forensic anthropologist for research?

A. universities
B. coroner's offices
C. governments
D. military

Answers

The answers would be:

Pelvis

Coroner's office

Here is more about your questions:

The pelvis is a good identifier when it comes to male and female because the features have distinct features. The female pelvis for example is broader and the inlet is much wider. It is structured that way to prepare the woman's body for pregnancy and child birth.

Forensic anthropologists is a sub-category of anthropology. Forensic anthropologists examine skeletal remains to determine how an individual lived, died, and how long they were dead. They can also identify who they were. Forensic anthropologists can assist especially when the remains are badly decomposed.

Bone that a forensic anthropologist will analyze to identify a victim as male or female is pelvis (A).

Coroner's offices (B) most likely employs a forensic anthropologist for research.

Further Explanation:

Pelvis is a complexes of bones that links the trunk and the legs. Pelvis also has paired hipbones that are connected in front and behind at the pubic symphysis and the sacrum, respectively. The three bones are illium, ischium and the pubis. All the three bones are united at the triangular suture called as acetabulum. Female pelvis have distinct feature as it forms a ring which acts as the birth canal.

Tibia is present in the lower leg of vertebrates. It forms the lower half of the knee joint in humans.

Humerus is the upper limb long bone that forms shoulder joint above and elbow joint below present in the land vertebrate.

The sternum is a long and flat bone that act as significant part of the rib cage and helps in stabilizing the thoracic skeleton. It is also involved in protecting various vital organs of the chest.

The main role of coroner is to probe the identity of unknown individual found dead in corner jurisdiction. Forensic anthropologist inspect the skeletal remains so as to reveal how an organism lived, died and the time duration till when it was dead.
