The statement "if pathogens invade your body, many of them are carried to the lymph nodes to be destroyed" is True.

When pathogens invade the body, many of them are carried to the lymph nodes to be destroyed. Lymph nodes are small, bean-shaped structures distributed throughout the body and are part of the lymphatic system. They play a crucial role in the immune response by filtering lymphatic fluid and trapping pathogens, foreign substances, and abnormal cells. Within the lymph nodes, immune cells such as lymphocytes and macrophages work to identify and destroy these pathogens, helping to prevent the spread of infection.

P=0.68 for A set of biology exam scores are normally distributed with a mean of 70points and a standard deviation of 6 points and x represent the score on a randomly selected exam from this set.

mean=70, standard deviation = 6.

from the table, z value = 1 and it is 0.15866.

P(x<64)=0.15866.

Similarly, the value for z=0.67 is 0.84134, so

P(x<76)=0.84134

thus, P(64 < x < 76) = 0.84134 - 0.15866 = 0.68268

A measure of a group of values' friction or dissipation in statistics is called the standard divition. When the standard divagation is low, the values are more likely to fall within a narrow range, also known as the anticipated value, whereas when the SD is high, the values tend to be near to the mean. The lower case Greek letter sigma, which stands for the population SD, or the Latin letter s, which stands for the sample SD, are most constantly used in fine equations and textbooks to represent SD.

The 6-month euro/yen forward price is 0.0201185 €/¥.

The 6-month yen/euro forward price is 49.7307 ¥/€.

To calculate the forward prices, we need to consider the interest rate differentials between the two currencies.

1. Calculate the euro/yen forward price:

  Forward price = Spot price × (1 + Euro interest rate) / (1 + Yen interest rate)

  Forward price = 0.02 × (1 + 0.04) / (1 + 0.01)

  Forward price = 0.0201185 €/¥

2. Calculate the yen/euro forward price:

  Forward price = 1 / Euro/yen forward price

  Forward price = 1 / 0.0201185

  Forward price = 49.7307 ¥/€

Therefore, the 6-month euro/yen forward price is 0.0201185 €/¥, indicating the amount of yen needed to buy one euro in the future. The 6-month yen/euro forward price is 49.7307 ¥/€, indicating the amount of euros needed to buy one yen in the future.

These forward prices are determined based on the interest rate differentials and expectations of future currency exchange rates.

Answer: Chloroplast

Explanation:

Plants and some algae have chloroplasts responsible for photosynthesis. Plants undergo photosynthesis to transform light energy into chemical energy. This energy is stored in the form of sugar to support their growth and provide energy. Chloroplasts have a double membrane, with the thylakoid membrane located within the inner membrane.

Photosynthesis occurs within the thylakoid membrane, which is folded into sacs called thylakoids. Chlorophyll, a green pigment, is present in the thylakoids and it absorbs light energy to split water molecules into hydrogen and oxygen. The oxygen is released into the atmosphere while the hydrogen is used to create ATP, a molecule that stores energy. ATP and hydrogen are then utilized to make sugar, the final product of photosynthesis.

OD. Add another layer of thermally non-conducting material to minimize heat loss.

Sam should add another layer of thermally non-conducting material to minimize heat loss and keep the food warm for a longer time. The first layer of thermally non-conducting material helps to reduce heat loss, but it may not be enough to keep the food warm for an extended period. Adding another layer will provide an extra barrier to prevent heat loss. It is important to note that the metal container is also an important factor in keeping the food warm as it can retain heat. Therefore, Sam should choose a metal container that is thick enough to retain heat and has a good lid to prevent heat loss. In summary, adding another layer of thermally non-conducting material to the metal container will help keep the food warm for a longer time.

The expected ratio of white to yellow seeds is 3:1, with 75 white seeds and 25 yellow seeds expected among the offspring. The total number of seeds produced would be 400.

The given information states that in maize plants, the allele M for white seeds is dominant over the allele m for yellow seeds, and 100 heterozygous plants were self-pollinated, producing 250 yellow seeds. We can use the Punnett square to determine the expected ratio of white seeds to yellow seeds among the offspring of these plants. The genotype of the heterozygous parent can be represented as Mm, where M represents the dominant allele for white seeds and m represents the recessive allele for yellow seeds. The Punnett square for the self-pollination of two heterozygous plants can be represented as:

                                                           M m

                   M                                     MM     Mm

                   m                                     Mm      mm

From the above Punnett square, we can see that the expected ratio of white to yellow seeds is 3:1, with three-fourths of the offspring expected to have the dominant allele (M) and produce white seeds, and one-fourth of the offspring expected to have the recessive allele (m) and produce yellow see. Therefore, we can expect 75 white seeds (3/4 of 100 seeds) and 25 yellow seeds (1/4 of 100 seeds) among the offspring. The total number of seeds produced by the self-pollination of 100 heterozygous plants would be 100 x 4 = 400.
