The examples of Washoe and Binta Jua show that animals:
a. may be able to apply rules and standards to situations
b. may have some capacity for moral behavior
c. have some sense of duty
d. can cultivate the full range of virtues

Answers

The examples of Washoe and Binta Jua show that animals may have some capacity for moral behavior.

The true choice is B.

Washoe, a female chimpanzee was the first animal to learn to communicate using American sign language, as part of animal studies to determine their ability to learn the language.

Binta Jua is a gorilla who has caught the world's attention by saving a boy's life. A child is known to have fallen more than 20 meters into the gorilla's habitat at the Brookfield Zoo in Chicago, Illinois. When she learned about this incident, Binta Jua immediately ran to save the child and lifted her with her strong arms. He then carried her to a safe place and held the child like his own.

The examples of the two animals can be categorized as moral behavior. Binta Jua had managed to save a child and Washoe had the animal's mental level to learn the language.

If you are watching a bird fly from one tree to another, the _____ is responsible for tracking that object.
red nucleus
thalamus
suprachiasmatic nucleus
superior colliculus
hypothalamus

Answers

The correct option is  A; Red nucleus , If you are watching a bird fly from one tree to another, the Red nucleus is responsible for tracking that object.

Anatomists have long debated the anatomical nature and content of the red nucleus. This midbrain region is vital for movement, and numerous theories propose that it changed drastically with the evolution of bipedalism.

Because there is still considerable disagreement in the scientific community about this structure, this article will concentrate exclusively on the anatomical and functional properties that have been agreed upon within the arena.

The efferent and afferent pathways, gross anatomy, and clinical points associated with the nucleus will be highlighted in particular.

Which of the following most likely would be an immediate result of growth factor binding to its receptor?
a. protein kinase activity
b. adenylyl cyclase activity
c. GTPase activity
d. protein phosphatase activity
e. phosphorylase activity

Answers

Protein kinase activity would be an immediate result of growth factor binding to its receptor.

Thus, the correct answer is A.

What is the growth factor?

Growth fаctors аre smаll extrаcellulаr ligаnds thаt trаnsmit signаls between cells аnd their environment. They cаn control cell function by binding to trаnsmembrаne receptors, аctivаting а myriаd of different intrаcellulаr signаling pаthwаys. Growth fаctors commonly bind to the receptor tyrosine kinаse fаmily of trаnsmembrаne receptors (RTKs).

RTKs hаve аn extrаcellulаr domаin thаt binds to ligаnd, а trаnsmembrаne domаin, аnd аn intrаcellulаr domаin thаt hаs tyrosine kinаse аctivity. Once bound to ligаnd, the RTKs dimerize, аnd trаnsphosphorylаte on tyrosine residues. This usuаlly leаds to the binding of аdаpter proteins to the phospho-tyrosine residues, leаding in turn to а cаscаde of events within the cell.

Carbon forms the basis of all the following except _____.

Choose one:

-fats

-nucleic acids

-sugar

-metals

Answers

pretty sure it’s metals!!
Metals is the correct answer.

Carbon forms the basis of all the following: fats, nucleic acids, and sugar. However, metals are not formed from carbon.

Carbon is a chemical element that is the building block of all known life on Earth. It is a highly versatile element that can form a wide variety of compounds, including fats, nucleic acids, and sugars. Fats and oils are composed of long chains of carbon atoms bonded to hydrogen atoms, and they are important sources of energy for living organisms. Nucleic acids are complex molecules that carry the genetic information for living organisms, and they are made up of long chains of nucleotides, which are composed of carbon, hydrogen, oxygen, and nitrogen atoms. Sugars are simple carbohydrates that are composed of carbon, hydrogen, and oxygen atoms, and they are important sources of energy for living organisms.

Metals, on the other hand, are a class of chemical elements that are characterized by their ability to conduct electricity and heat, and they are not composed of carbon. Some examples of metals include copper, gold, iron, and silver.

Answers

The minerals of the olivine group such as tephroite are used for a umber of different purposes such as in the conditioners, for the making of jewellery.

What are the uses of Tephroite?

Tephroite is the manganese end-member mineral of the olivine group of  the nesosilicate minerals. The formula of Tephroite is Mn₂SiO₄. It is a solid solution series which exists between the tephroite and its analogue mineral substances, such as the group endmembers fayalite and forsterite. Divalent iron or magnesium atom may readily replace the manganese atom present in the olivine crystal structure of the tephroite because of their higher reactivity than manganese atom.

Most of the olivine group minerals are used in the metallurgical processes in the blast furnace. The high-magnesium olivine that is forsterite is added to the blast furnaces to remove impurities from steel and to form aconditioner. Olivine group minerals also have been used as a refractory material. These minerals are used to make refractory brick and are also used as a casting sand.
