O a luminous object is stationary compared to an observer
Pls help I will give 21 points if it is correct
Answer:
(b) a distant luminous object travels rapidly towards an observer.
Explanation:
Blueshift is observed when a distant luminous object travels rapidly towards an observer. The correct option is B.
What is blueshift?The displacement of an approaching celestial body's spectrum toward shorter wavelengths is known as blueshift.
When an object moves away from us, the light it emits is known as redshift; when an object moves towards us, the light it emits is known as blueshift.
The blue and red shift of stars cannot be seen with the bare eye. There are several reasons for this.
First, even for an object moving at thousands of kilometers per hour, the effect is minor, with only a slight change in hue.
Red light, with both the longest wavelength, is at one end of the spectrum.
The shortest wavelength is blue or violet light. White light is a blend of all the colors in the color spectrum. It has every color of the rainbow.
Thus, the correct option is B.

what are some reasons implicit stereotypes might differ from explicit stereotypes?
Answer:
Implicit stereotypes are automatically activated and operate indirectly, and thus individuals may not be aware that they possess such beliefs. In contrast, explicit stereotypes are accessible to conscious awareness and are what individuals report when asked about group differences.
Explanation:
Please rate, thank me, have a good day
Implicit stereotypes operate automatically and indirectly, so people may not realize they have them. When asked about group differences, people report explicit stereotypes.
What are stereotypes?A stereotype is a preconceived notion or combination of traits that many people hold to be indicative of a certain kind of person or object. Stereotypes are traits that society automatically ascribes to particular groups of people in order to categorize them according to factors like age, weight, occupation, skin tone, gender, etc.
Since implicit stereotypes function subtly and automatically, people may not even be aware that they hold such beliefs. Conversely, explicit stereotypes are cognizable and are what people report when questioned about group differences.

Explanation:
You have recently identified a new toxin. It is produced by a gram-negative bacterium. It is composed mostly of protein, has high toxicity, and is not heat stable. You also discover that it targets liver cells. Based on these characteristics, how would you classify this toxin
Based on the characteristics above, this toxin can be categorized as EXOTOXIN. These toxins (exotoxins) are produced by different types of bacteria.
Exotoxins are a broad category of proteins produced by bacteria that enter host cells in order to alter their physiological properties.
These toxins (exotoxins) can be secreted by Gram-negative bacteria and Gram-positive bacteria.
Examples of exotoxins include botulinum toxin secreted by Clostridium botulinum bacteria, tetanospasmin toxin secreted by Clostridium tetani bacteria, etc.

How do differences between the peaks and valleys of the two graphs demonstrate interactions between these populations?
Answer:
peaks and valleys show population increase and decrease between 2 species or more.
Explanation:
the peaks and valleys are used to show predation hence if there is an increase in prey there will be an increase in the predators and if there is a decrease in prey there will be a decrease in predators therefore creating peaks and valleys in that graph hence demonstrating population interactions between the two species.

Answer:
Adrenaline
Explanation:
The adrenaline glands, located on top of both kidneys, are glands that produce hormones to regulate blood pressure, bodily functions, metabolisms, etc. Adrenaline is released whenever the blood is redirected towards the muscles, causing surges of energy. In general, adrenaline increases blood flow in your body, which causes the heartbeat to increase, or give the feeling of a racing heart. Between the football players and the heartbeat rate, they are getting rushes of adrenaline from either participating in the game or cheering on their team from the sidelines. Hope that made sense.

LEADING cause of the loss of biodiversity? (SEV5.a) *
O a. Extinction
O b. Habitat Loss
O c. Pollution
O d. Overexploitation
Answer:
your answer is B. Habitat Loss
Explanation:
What is the #1 cause for the loss of biodiversity?
Habitat destruction
Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.
Habitat loss and overexploitation, driven by our rapid population growth and unsustainable consumption patterns, are the primary causes of biodiversity loss which is now happening up to ten thousand times faster than for millions of years before.

the nerve impulse is an electrical current that travels along dendrites or axons.
Answer:
i think your answer is true! :)
Explanation:
The statement: The nerve impulse is an electrical current that travels along dendrites or axons is true.
Dendrites are the branched projections of a neuron that receive signals (chemical or electrical) from other neurons or from sensory cells. They are often referred to as the input zone of the neuron, as they receive and integrate incoming signals from other neurons.
A nerve impulse is an electrical signal that travels along the dendrites or axons of a neuron. When a neuron is stimulated, it generates an electrical charge that spreads along its membrane, causing an action potential.
This electrical signal then travels along the axon of the neuron, where it can be transmitted to other neurons or to muscle cells or glands. The speed at which the nerve impulse travels can be influenced by factors such as the diameter of the axon, the presence of myelin sheaths, and the concentration of ions inside and outside of the neuron.Therefore, the mentioned statement about the nerve impulse is true.
