Simple cells have been originally described by the existence of segregated subregions inside their RF that respond to both the on- or offset of a light bar and with the aid of spatial summation inside every of these regions, whereas complex cells had ON and OFF areas that had been coextensive in space [Hubel DH, et al.

Unlike the simple cortical cells, which respond to small sports of light or to stationary stimuli, complex cortical cells reply excellent to bars that are oriented across the receptive field. End-stopped cortical cells reply quality to corner, angles, or bars of a positive length shifting in a specific direction.

A simple cell responds to all wavelengths whereas complex cells respond only to wavelengths in their particular wavelength tuning.

Answer:a chemical change must occur to change states

Explanation:

Chemical changes are irreversible, physical changes however dont affect the structure of the molecule of whatever it is

Answer:

Hey!

Your answer is A: Heat must be added or removed

Explanation:

For example...

To change water from a liquid to a solid, you have to change its molecular composition and change the bondages between the Hydrogen and Oxygen molecules...

This is only done when you add heat / remove through Vaporization / Condensation!

To change a substance's state is a REVERSIBLE process meaning you have to add or remove energy (heat) to change its state!

Dendritic cells and macrophages ingest and break down foreign substances and cellular waste in a process known as phagocytosis. An essential function of the immune system is phagocytosis, in which specialised cells called phagocytes identify and take in foreign substances like pathogens or cellular waste in order to remove them from the body.

The capacity to grow pseudopodia around the target material by macrophages and dendritic cells creates a phagosome, which is then internalised by the cell.

The phagosome joins with lysosomes to create a phagolysosome, where the substance it has absorbed is digested and destroyed by enzymatic processes.

Gas moves freely and vibrates at great speeds. Liquid moves, vibrates, and slides past one another. Although solid objects vibrate (jiggle), they often do not move.

The molecules in the solid vibrate stationary. Liquid Particle in a liquid flow as well as glide across one another, but they tend to settle near the bottom of the vessel. Although the attraction interactions among particles were also capable of holding a certain volume, they are insufficient to prevent molecules from sliding on top of one another.

A solid seems to have a distinct volume and shape. Despite taking on the shape of its container, liquids have defined volumes. Both a volume and a defined shape are absent from a gas. Although the particles of plasma were extremely far apart, unlike those of a gas, which are electrically isolated, plasma contains a charge.

Explanation:

The method of reproduction in honeybee colonies, known as swarming or colony division, has several advantages for the colony; Increase in colony size, Genetic diversity, and reproduction.

Swarming allows the honeybee colony to increase its population and overall size. When a colony becomes overcrowded, the queen and a portion of the worker bees leave the original hive to form a new colony, taking with them the resources needed to establish a new colony.

Swarming helps in promoting genetic diversity within honeybee colonies. When a colony swarms, the original queen leaves with a group of workers, and a new queen is raised in the original hive from eggs laid by the existing workers.

Swarming is a natural means of colony reproduction, allowing honeybee colonies to reproduce and potentially establish new colonies in different locations. This increases the chances of survival and reproduction of the honeybee colony as a whole, as it can establish new colonies in favorable locations with ample resources.

The solution is False. The reason this is false is because: The deep zone does not begin at the depth of 3300 feet. The right answer is false.

The deep zone of the ocean actually begins at a depth of around 6600 feet (2000 meters). The depth of 3300 feet (1000 meters) marks the beginning of the mesopelagic or "twilight" zone.

The deep zone of the ocean, also known as the deep sea or the abyssal zone, is the layer of water in the ocean that extends from a depth of about 3,300 feet (1,000 meters) down to the ocean floor, which can be as deep as 36,070 feet (10,994 meters) in some places.

Answer:

A. Similarities between mitosis and meiosis include: 

both are processes of cell division or the creation of daughter cells from a parent cell

both go through the phases: prophase, metaphase, anaphase, and telophase and cytokinesis

both use most of the same machinery of cell division including centrosomes, spindle fibers, etc.

B. Differences between mitosis and meiosis include:

Meiosis is used in sexual reproduction to make four haploid (n) daughter cells from one parent cell. 

Mitosis is used for growth, replacing old cells, and asexual reproduction. One parent cell makes more 

Meiosis happens in two stages, or two rounds of division, known as meiosis I and meiosis II. Mitosis only involves one round of division, or division of the cytoplasm.

During meiosis, crossing over occurs, which increases the genetic variation of gametes. This does not happen in mitosis. 

The probability of both traits appearing in the same offspring is (3/4) x (3/4) = 9/16 and the probability of both traits appearing in the same offspring is (1/4) x (1/4) = 1/16.

Traits are defined as specific characteristics or attributes of an individual.

1. To calculate the expected values, we need to multiply the total number of progeny by the probabilities of each phenotype. The expected values are:

315 Round, Yellow Seed = (556) x (9/16) = 311.5

108 Round, Green Seed = (556) x (3/16) = 104.5

101 Wrinkles, Yellow Seed = (556) x (3/16) = 104.5

32 Wrinkled, Green Seed = (556) x (1/16) = 34.5

2. Chi-Square Analysis:

The chi-square test is used to determine whether the observed data fits the expected data. The formula for the chi-square test is:

χ² = Σ [(O-E)²/E]

Where:

χ² = chi-square value

O = observed frequency

E = expected frequency

We can calculate the chi-square value for this data as follows:

χ² = [(315-311.5)2/311.5] + [(108-104.5)2/104.5] + [(101-104.5)2/104.5] + [(32-34.5)2/34.5]

χ² = 1.01 + 1.69 + 0.84 + 0.39

χ² = 3.93

3. Degrees of freedom (df) = (number of phenotypes - 1) = 3

Using the chi-square distribution table with 3 degrees of freedom and a significance level of 0.05, the critical value is 7.815. Since our calculated chi-square value (3.93) is less than the critical value (7.815), we fail to reject the null hypothesis.

4. Null Hypothesis:

The null hypothesis is that the observed data fits the expected data, meaning that the traits are independently assorted.

7. Calculating the number of times DNA must condense itself during mitosis:

If the chromosome is 2 μm long and contains about 1.5 cm of supercoiled DNA, then the DNA must condense itself by a factor of 1.5 cm / 2 μm = 7500 times during mitosis.

8. Calculating the length of DNA in the uncondensed form:

If the chromosome is 2 μm long and contains 1.5 cm of DNA, then the length of DNA in the uncondensed form is 1.5 cm / 2 μm = 750,000 μm or 750.

Anemia is a condition that may be caused by iron deficiency. The normal red blood cells in the blood contain hemoglobin, which is a protein that binds to iron and transport oxygen to different parts of the body. People with anemia by iron deficiency have hemoglobin levels lower than normal, and therefore they can't transport enough oxygen to the tissues. The anemia by iron deficiency is a condition that can be treated by consuming foods rich in iron such as dark green leafy vegetables (i.e., chard, spinach, etc), red meats, beans, dried fruits, seafood, etc.

Corals glow because they contain tiny algae called zooxanthellae. These algae live inside the coral's tissues and provide the coral with food and oxygen.

How to explain the information

In return, the coral provides the algae with a safe place to live and carbon dioxide. When the water temperature gets too warm, the algae start to die. This causes the coral to lose its food source and turn white, a process called bleaching.

If we don't take action to reduce greenhouse gas emissions, the oceans could be too warm for any corals to survive in as little as 30 years.

About half of the coral reefs on the Great Barrier Reef have died in the past 30 years.

Richard is optimistic because he believes that we can still save the coral reefs if we take action to reduce greenhouse gas emissions and protect coral reefs from other threats such as pollution and overfishing.
