Answer:
The article revealed the fact that Black inventors have always played an active role in inventing new things in America. In the 18th and 19th centuries they were denied the right to patent their inventions because of their status as slaves. This has changed for the better in present times as many Black inventors are being granted patent rights.
Explanation:
The article, "America’s always had black inventors – even when the patent system explicitly excluded them", by Shontavia Johnson, explained the active role that Black Americans, both free and slaves played in inventing things in the United Slaves. The article explained that although the patent rights signed into the constitution in 1787 was written in a neutral tone, it did not change the fact that black inventors were actually denied patent rights.
This segregation affected people like Henry Boyd, Ned, Benjamin Montgomery among others. In recent times, this segregation has significantly been curbed as many Black inventors are now owners of patents. An example is Lonnie Johnson, inventor of the Water Gun and owner of more than 80 patents.

Help a mate out in biology
Answer:
A. Spores
B. Meiosis
C. Spores grow by mitosis into gametophyte
D. Haploid (n)
E. Gametes (sperm and egg)
F. Mitosis
Explanation:
Alternation of generations is a system of life cycle exhibited by certain organisms such as algae, plants etc where they alternate between a haploid phase/generation and diploid phase/generation. In this life cycle, the SPOROPHYTE is the diploid (2n) multicellular body that forms haploid SPORES via meiotic division. These spores, however, grow into another multicellular body via mitosis called GAMETOPHYTE.
The GAMETOPHYTE refers to the haploid (n) body that produces the haploid gametes (sperm and egg) by undergoing mitosis. The haploid gametes produced unites in a process called FERTILIZATION to yield a diploid ZYGOTE that eventually mitotically grows into the SPOROPHYTE. Note that, the cycle repeats.

There is an incline in the amount of nutrients and a decrease in solidification.
There is a decline in the amount of nutrients and an increase in solidification.
Answer:
There is a decline in the amount of nutrients and an increase in solidification.
Explanation:
There are many layers that constitute the formation of the soil. The layers of the soil are termed as horizons. The upper layer or the topsoil is rich in organic matter. The dead and decaying matter are constituted in the upper layer. Below each layer the level of organic material decreases. The bottom layer is the bedrock. The soil becomes hard and tough from top to bottom.
Answer:
There is a decline in the amount of nutrients and an increase in solidification.
Explanation:
The correct answer is There is a decline in the amount of nutrients and an increase in solidification. The top layers of soil are rich in nutrients but are very malleable. As the layers go deeper into the Earth, the nutrient content drops while the soil becomes harder.

What is the correct sequence of molecules involved in protein synthesis from beginning to end?
mRNA → tRNA → DNA → Protein
mRNA → tRNA → DNA → Protein
DNA → mRNA → tRNA → Protein
DNA → mRNA → tRNA → Protein
DNA → mRNA → Protein → tRNA
DNA → mRNA → Protein → tRNA
tRNA → Protein → mRNA → DNA
Answer:
DNA → mRNA → tRNA → Protein
DNA → mRNA → tRNA → Protein
Explanation:
This is because during protein synthesis, DNA is use to make RNA in the process called transcription. The DNA double strand is unwind by an enzyme called RNA polymerase to produce mRNA in the nucleus. The trans is produced in the nucleolus by RNA polymerase 1 and the site then binds aminoacyl tRNAs which is assembled in the RIBOSOMES. The tRNA are then translated into protein.

which steps of the greenhouse effect are most affected by the increases in greenhouse gases, leading to increase in heat?
Answer: Greenhouse gases arise naturally, and are part of the make-up of our atmosphere. Earth is sometimes called the “Goldilocks” planet – it’s not too hot, not too cold, and the conditions are just right to allow life, including us, to flourish. Part of what makes Earth so amenable is the naturally-arising greenhouse effect, which keeps the planet at a friendly 15 °C (59 °F) on average. But in the last century or so, humans have been interfering with the energy balance of the planet, mainly through the burning of fossil fuels that give off additional carbon dioxide into the air. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades and traps extra heat near the surface of the Earth, causing temperatures to rise.

When a weather forecaster predicts a "low pressure system will pass through the area, what type of weather should be expected? (1 poi
A. sunny, fair weather
B. much colder weather
C. a severe storm such as a hurricane
D. clouds and possible precipitation
When a weather forecaster predicts that "a low pressure system will pass through the area, cloudy and potentially rainy weather should be expected". So, the correct option is (D).
What is Weather?Weather is defined as a mixture of events that occur every day in our environment that vary in different parts of the world and vary over a period of minutes, hours, days and weeks. Most of the weather occurs in the troposphere, the part of Earth's atmosphere that is closest to the ground.
Weather is controlled by changes in air pressure, so air pressure is caused by the weight of the large number of air molecules that make up the atmosphere. Thus, when the sky is clear and blue when the air pressure is high where high pressure causes the air to flow downward and when it reaches near the ground it prevents clouds from forming and when The air pressure is low so the air flows together and then moves upwards where it converges, rises, cools and forms clouds.
Thus, when a weather forecaster predicts that "a low pressure system will pass through the area, cloudy and potentially rainy weather should be expected". So, the correct option is (D).

Rose conducted an experiment to study the effect of temperature change on the heart rate of Daphnia, transparent aquatic invertebrates commonly known as water fleas. She heated three different beakers of water containing Daphnia to a different temperature: 30°C, 32°C, and 34°C. She put a drop of water from each beaker on a slide mount and used a microscope to observe Daphnia in each sample. She counted the number of heartbeats in one minute and averaged her results. Which of the following could be a step in a replication of this experiment?
Answer:
Rose's classmate Mina observing Daphnia in water at 30°C, 32°C, and 34°C.
A step in replication of Rose's experiment could be to repeat the procedure of heating three different beakers of water containing Daphnia to 30°C, 32°C, and 34°C, counting the number of heartbeats in one minute for each sample using a microscope and slide mount, and averaging the results.
What is Daphnia?Daphnia, also known as water fleas, are small, transparent aquatic invertebrates that are commonly used in scientific experiments to study the effects of environmental factors on living organisms. In many experiments, Daphnia are subjected to changes in temperature, light, oxygen levels, and other variables to determine how these changes impact their behavior and physiology.
One example is studying the effect of temperature on heart rate, as done by Rose in the experiment described above. The use of Daphnia in experiments is beneficial because they are easy to culture, reproduce quickly, and are small and simple enough to be easily manipulated in the laboratory. Additionally, because Daphnia are freshwater organisms, they are particularly sensitive to changes in their environment, making them useful for investigating the impacts of various stressors on aquatic ecosystems.
