Newly hatched birds that lack down and are nest-bound, unable to feed on their own, as with baby wrens or robins, are Group of answer choices carinate. altricial. derived. ratites. precocial.
Newly hatched birds that lack down and are nest-bound, unable to feed on their own, as with baby wrens or robins, are ALTRICIAL. These species include hummingbirds, swallows, passerine birds, woodpeckers, etc.
In altricial species, young individuals are underdeveloped at birth, thereby needing the help of parents to mature and develop into adult individuals.
Conversely, precocial species are species in which young individuals are mature and mobile from the moment of birth.
Most domestic species of birds (i.e., ducks, turkeys, chickens, etc) have a precocial type of development.

A 160 lb. college student consumes a bowl of cereal containing 750 Calories in the morning. He then sits quietly in class for 4 hours, and then goes for a 30-minute run. How many Calories did he use, and was it more or less than he consumed?
Answer:
less
Explanation:
because a 30 min run can only burn 200-500 calories
In the morning, a 160-pound college student consumes a bowl of cereal with 750 calories. 30 minutes of running can only burn 200-500 calories.
What is Calories?The calorie is a type of energy unit. For historical reasons, there are two main definitions of "calorie." The large calorie, food calorie, or kilogram calorie was originally defined as the amount of heat needed to raise the temperature of one kilogram of water by one degree Celsius.Calories are the units of energy released by your body when it digests and absorbs food. The higher the calorie content of a food, the more energy it can provide to your body. When you consume more calories than you require, your body stores the excess calories as fat. Even fat-free foods can be high in calories.

Choose the answer that correctly lists, in chronological order, the events involved in synaptic transmission.
a: A nerve impulse reaches the synaptic knob.
b: Neurotransmitter molecules diffuse across the synaptic cleft.
c: A nerve impulse begins in the postsynaptic cell.
d: Neurotransmitter molecules bind to receptors in the postsynaptic cell.
e: A voltage change occurs in the postsynaptic cell.
Answer: hi im brain bot
im not sure i know this one im stumped
Explanation:
The event occurs as nerve impulse reaches the synaptic knob, neurotransmitter molecules diffuse across the synaptic cleft. These molecules bind to receptors in the postsynaptic cell and voltage change occurs in the postsynaptic cell. A nerve impulse begins in the postsynaptic cell. The correct option is C.
What is synaptic transmission?The metabolic pathway by which a neuron interacts with a target cell across a synapse is known as synaptic transmission.
Chemical synaptic transmission is characterized by the release of a neurotransmitter from the presynaptic neuron and the binding of the neurotransmitter to specific post-synaptic receptors.
Synaptic transmission is the process by which a nerve impulse (action potential) travels from the presynaptic neuron to the post-synaptic neuron across the synaptic gap. An action potential is an electrical impulse that travels down the axon of a neuron.
As the nerve impulse arrives at the synaptic knob, neurotransmitter molecules diffuse across the synaptic cleft. These molecules bind to receptors in the postsynaptic cell, causing voltage changes in the cell. and finally nerve impulse begins in the postsynaptic cell.
Thus, the correct option is C.

The cell in the diagram is a plant cell because it has chloroplasts and a cell wall.
There are two types of cells animal cells, which are the ones that humans and animals have, and plant cells, which are the ones that plants and trees have. They share some organelles, but they also have some that are specific to each type.
The plant cell parts in the picture are:
Rough Endoplasmic Reticulum: it is where the ribosomes are. The synthesis of proteins happens there.Chloroplast: it is an organelle-specific of plant cells. They are in charge of photosynthesis.Cell wall: it is only present in plant cells. It surrounds the membrane.Mitochondria: It is the place that generates the energy that the cell needs.Vacuole: they are bigger in cell plants than in animal plants. It has many functions, but one is to store water.Membrane: it draws the limits of the cell.Golgi Apparatus: it is the place where proteins go to be distributed.Nucleus: it contains DNA, and it has a membrane around it.The nucleolus: is the larger part of the nucleus. It is in contact with the endoplasmic reticulum.To sum up, the plant cell has a bigger vacuole than the animal cell; it also has chloroplasts and a cell wall, which are not present in the animal cell.

How can I use the analogy of building blocks to explain how genes relate to the diversity of life?
Answer:
-Building blocks are the fundamentals to an overall result, in this case being the characteristics of a human being.
-This is related to genes as the variety of building blocks can make a completely different "outcome" just as a different gene can trigger a different characteristic.
- Without different building blocks, all outcomes will be the same, just as humans. So a variety of "building blocks" are needed for diversity.

How many carbon atoms does glucose have
Answer:
six carbon atoms
Explanation:
Glucose has an aldehyde group (-CHO) on carbon atom number one and is therefore called an “aldose,” also it has six carbon atoms (a hexose) so it can be called an “aldohexose.” The reactive group on fructose, however, is a ketone group (-C=0) on carbon number two.

The study of the properties and changes in matter and their relation to energy
a. Physical Chemistry
b. Biochemistry
c. Organic Chemistry
d. Inorganic Chemistry
Organic chemistry is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds. Most organic compounds contain carbon and hydrogen, but they may also include any number of other elements (e.g., nitrogen, oxygen, halogens, phosphorus, silicon, sulfur).
The study of the characteristics and changes of matter, as well as the interactions between matter and energy, is the focus of the field of chemistry known as physical chemistry. Therefore, the correct option is A.
It integrates ideas from physics and chemistry to understand the molecular behavior of molecules and atoms. Thermodynamics, kinetics, quantum mechanics, spectroscopy, and statistical mechanics are among the subjects studied by physical chemists.
Their work advances many disciplines, including biology, chemical engineering and materials science. By understanding the fundamental ideas of physical chemistry, scientists can create new materials, predict and explain chemical reactions, and understand the subtleties of molecular interactions in many systems.
Therefore, the correct option is A.

•Oxbow lake. Eroison by rivers
•Alluvial fan
•Delta
•Meander. Deposition by rivers
•Waterfall
•Flood plain
Deposition by rivers generates alluvial fans and deltas. Moreover, erosion by rivers generates waterfalls, flood plains, oxbow lakes and meanders.
An oxbow lake is a lake located in a meandering channel, and therefore on a floodplain.
Alluvial fans are accumulations of sediments created as flowing water bodies interact with mountains or hills.
A delta is a formation of land composed of sediments located in the mouth of the river.
A waterfall is a point in a river where water spills suddenly downward.
